Only after you trim it to..... say 1.6 the size it is now.
Sounds like you need a 1d body.

As noted by another poster, the 5D3 comes pretty close to being a full frame 7D (with even better AF and other bells and whistles).
No.
I like the notion of a 7DX that has 18 MP APS-H sensor at 10 fps using same AF as 5DIII. That should give a cleaner sensor than any APS-C and yet some decent crop advantage. The perfect compromise. I'd happily give up my one and only EFS lens.
And Canon would call that camera the 1D Mk IV.

IMO, anything that is called a "7D" should have pixel density higher than or equal to the original 7D, and use EF-s lenses. FF with bigger pixels is a huge step backwards for people shooting in focal-length-limited situations.
Why do people like you always want to hijack a line and make it into something else, which is in some ways inferior?

Which should start selling at decent used prices when there area lot of 5D3s and 1Dxes out there.
"7D" means APS-c, pixels 4.3 microns or smaller, and at least 8fps.
People wishing for larger formats should save their pennies or go into debt for the 5D3 or 1Dx, and leave the 7D series alone.
Me, personally, I want a 9D with a 2.5x to 3x crop and at least 18MP, more if the burst speed can keep up.

I did not know Canon already came out with the 5D Mark 3, it seems like 6 month ago they came out with the 2. What's the auto focus points on the 3, and is the shutter speed the same/faster than the 7D? I need the fast shutter speed on the 7D, not the slowness of the 5D2.

It is a puzzle why everyone does not see the obvious. For a long time, the 7D had the highest pixel density of any DSLR. Canon has let it slip to second or third recently.
Exactly.
That is what I hope for. The sensor in the Nikon V1 looks good with 2.7x crop and better than expected high ISO. Only 10Mp, but would be 29Mp at 7D size. 30Mp with 1.6x crop seems reasonable to expect soon. And 8fps.

It's been 3 years since the 5D2 came out. There are 61 AF points on the 5D3 and it has the same shutter lag as the 7D.

No they would not call it a 1DMkIV. A 1DMkIV is a full size extra heavy-duty pro body that's at least three years old. Maybe you need to adjust your viewing angle as last time I looked, the 7D is in a lot smaller body. Additionally, Canon has improved their sensor design and their AF units. I would want those improvements in a 7D/5DIII form size, not in a clunkier 1D pro body size. The 1D Mk IV has readily observed noise above ISO 800. How could you possibly think that I am asking for a 1D Mk IV,... just because of the APS-H sensor size?
I rather doubt you are an authority of what any future model designation means. A 1D Mk IV meant an APS-H sensor and a 1Ds meant a full-frame sensor. Now Canon has decided that 1DX means full-frame and is the replacement to both of those. How can you speak with authority that 7D means APS-C sensor unless you are making the rules up for Canon?
People should be allowed their opinions about future 7D successors.
This thread is discussing hypothetical 7D models. As we already understand the presence of the existing full frame models, and we have observed Canon resizing the sensor for the 1D Mk IV replacement, a hypothetical 7D replacement might have an APS-H sensor. I'm not going to leave the 7D alone as it too should evolve with technical advancements in feature improvements. The 1D Mk IV being replaced with 1DX means that there is now a possibility of a replacement in the APS-H sensor size.
I'd leave the 2.5x - 3x crops to the point-n-shoo, micro four-thirds, interchangeable lens categories as Canon has a hard enough time creating a decent sensor in the DSLR full-frame and 1.6x crops.

I am not the one calling it that. TTMartin did, and I responded that some of those will eventually be selling cheap. Please stop reading any lack of disagreement as total agreement. Of course the 1D4 is bigger and heavier than the 7D.
For high ISOs, mainly.
Who are you replying to? Perhaps you should have had two posts; one to reply to TTMartin, and one to reply to me.
I don't know what stupid decisions Canon will make, but I know what is logical, and I know what I and what some others need; a successor to the 7D that doesn't have larger pixels. The 7D's pixels are huge for sharp lenses and good technique.
1Dx is a downgrade from the 1D4 and the 1Ds3 to the focal-length limited user, or the person who wants lots of resolution. A new number like '2" should have been used.
Look, going to a bigger sensor as a compulsion is stupid. We need cameras with higher pixel densities, and Canon seems to be going the other way, catering to 14fps people and videographers.
Including me, or am I excluded?
That won't do a lot of people any good. People who really understand the issues know that focal-length-limited shooting requires higher pixel densities, not bigger sensors. My small bird photography is not going to benefit as much from an APS-H 7D successor as it will from an APS-C 7D successor with higher pixel density. I'd have to use a TC more to get the subject spread out over more pixels, and then I'd have to raise the ISO, totally negating the extra light-capturing ability of the bigger sensor, plus I now have more artifacts from the extra glass, and AF may not be available or is compromised with the TC.
Actually, Canon has traditionally used Sony sensors for their small-sensor cameras, and a Sony Exmor would do just fine. Sony expects to halve the read noise of their small sensors with future stacked sensors. Current P&S sensors resolve much more per mm than Canon CMOS DSLR sensors, with similar noise at high ISOs, and much lower noise at low ISOs. There is no doubt that an Exmor sensor with a pixel density 4x that of the 7D would trash a similar sized crop from the 7D at low ISOs, and be marginally better at high ISOs for noise, and have much more detail.
The problems that Canon has with pattern noise and post-gain noise has nothing to do with pixel density, and many tiny sensors do not show such problems to anywhere near the degree that Canon DSLR sensors do. Have you ever seen the detail from a Pentax Q with a DSLR lens adapter with a sharp lens? None of the 4/3 sensor manufacturers have tackled noise, but that has nothing to do with the sensor size, because much smaller Sony sensors have less read noise. Panasonic and Olympus do not know how to get read noise down low, and this has nothing to do with sensor size.
Maybe you're forgetting the fact that much photography can not possibly be done at low ISOs. There's a limit to how fast a hand-holdable super-telephoto lens can be on an APS-C format, forcing high ISOs. A shorter, wider lens (or the same one without a TC) that is equally hand-holdable can be operated at a lower ISO, and the amount of noise at a lower ISO on a smaller sensor can be as low as the other-wise-needed high ISO with the slower glass on the larger sensor.
I am strongly expressing my opinion, because I think Canon seems to be ignoring people like me, and people like you are cheering them on with this "every sensor in every line should get bigger" nonsense.

John, I've never thought about this before but it does sound like a very interesting proposal.
riknash, It has to be a dslr for the intended purpose but I don't think people like you who has never used a 7D, or aps-c, for what it is best to be used for would understand this.

I agree with you John.
The more that the fanbois shout that their current technology "is good enough", the less incentive there is for Canon to drive improvements.
And it's not just about sensor size. Our local forum has a current lengthy discussion on dynamic range of Canon sensors and the consensus from the Canon shooters is that current DR is more than enough for most peoples needs.

The question isn't so much whether this is true or not but the attitude in general doesn't provide any incentive for Canon to improve this or any other important image attributes.

Zooms? pfffft!
he's trolling. and succeeding, it seems.
Yes, I was snippity yesterday. All better now 
This thread seems to have developed a bit more civility than what was the norm for the past while.

Riknash, why are you so snippity on here? Totally unnecessary. Just an observation.
Try to have a better day, for the sake of the rest of us...
