Why would the A55 offer 10 fps but the A580 only 7 fps? Does that indicate that the 7 fps is the existing A550's high speed mode with fixed exposure and focus and the A55 perhaps has dual processors? If it has dual processors will it likely be priced similarly to a Canon 7D (about $1500 currently)?
If these specs are accurate, what can we expect from the A7xx? 18 MP? 10 FPS? 40 AF points?
I know nobody has answers to these questions (at least nobody who is talking). I'm just expressing my curiosity.

A55 is suppose to be pellicle camera i.e. does not have a moveable mirror. Since there is no mirror to flip up and down for every picture it can take quicker pictures.

I believe the above is true so I would guess the shooting limit will be one of the processing pipeline. Perhaps the A5X has a better processing pipeline or they may have just limited the A3X for product separation reasons.

Ahhh, the wisdom of Spock. How very true. Within 6 months of the release of the A7XX, rumors about it's replacement will start to emerge. LOL And I'm as guilty as any of 'em. What the heck. It's a harmless (if somewhat expensive) obsession.

I understand the mirror thing but I was referring to what Rick suggests. My Canon 1D MkIV flips the mirror 10 times per second but still requires dual processors to process and move those 16MP files at 10 fps. Similarly the A900 requires dual processors to move those big 24+ MP files at 5 fps (compared to the single processor A850's 3 fps speed). So I'm thinking the A55 must have dual processors and that's going to be expensive.

Or yet another example would be your Canon 7D using dual processors to move those 18MP files at 8 fps.
Fortunately, Moore's law applies to data processors a lot more than it does to, say, image sensors. And with Sony being at, or at least close to, the forefront in that regard, hopefully this will keep the price of the A55 from being too outrageous. Assuming, of course, that the A55 rumor, along with its rumored 10 fps shooting capability, isn't just a bunch of BS in the first place.
I guess we'll find out soon enough ... --

The image presented in this thread is not equal to 'nothing'. Stop making up things.
Come on Walt, you don't know wether you will be alive next month or not, and that doesn't bother you, does it?

A year ago I was expecting it at this Photokina at the soonest, in a sea of "tomorrow for sure" predictions that turned out to be wrong. I based my prediction on what Sony had said at that time or previous. They have really said nothing new since.
With some of the latest rumors you will only get another prototype at Photokina and at least 6 months until actual product is on the shelves.
If it turns up at Photokina the question will be how prominently Sony displays it and supports it in the show? How many other things will be put in front of it by Sony. A whole lot, I expect, with the a7xx if it's there on some back shelf, mostly ignored by Sony.

4 more beginner level options, only one mid range if the a7xx actually is released.

Where are the four separate models at the mid range, a7xx level?
Just more beginner cams.

You mean there is a choice for advanced DSLR users looking for improved OVF and other still photography features and no video? Say like the a700 improved.
I don't think so.

I never owned one of the Canon (or other brands) designs. But I most certainly had fellow photographers I shot with who did. And at the time I ran the darkroom everyone used in our Army unit which brought in even more photographers. Delicate is the key word for that pellicle. It worked well enough, but was virtually unclean-able. And it got dirty too.
I've actually designed and built beam splitters (which is what the pellicle is) Though not ones for the SLRs. Mostly custom microscope gear and such for my own use. Many such for microscope work use the thinnest cover slip material instead of a membrane. Those are available in bulk so you would just toss them if they got dirty. Though long ago I did learn how to safely clean such thin optical glass.
If they expect to get a useful image from the light passing through the pellicle then it's got to be thin. Preferably infinitely thin so it's only one air/membrane surface. So I'm waiting to see if they really have abolished physics or not ;-) And flipping such a thin membrane sounds like a mighty short life too. At the speed it would have to flip that's relatively a lot of force applied on the membrane just moving the air.
Most certainly any time you have phase AF the pellicule has to be in there. Certainly for all the video, and maybe a good part of the stills too.
I consider these cameras as experimental at this point. I'd not call them the main path of DSLR until a good track record over time can be established. And I think that's why Sony did not stick them in the main DSLR model sequence.

August starts in one day. And there certainly people talking like these will be released in just a few nanoseconds ;-)
And I was just reminding folks that all of this is just unannounced rumors. Knowing Sony the news conferences will be over before anything shows on their announcement pages, which is where we mere (non press) mortals are supposed to look

I would hope there wouldn't be too much choice at the A7XX level - maybe just with and without video. If they segment it too much they will likely strip out some features for market differentiation. Not a good thing to do for a camera in this class IMO. As I think is clear from the "A700 buttons" thread - the A7XX series should be full featured to allow the advanced photographer to work they way they want to.

About as close as you can get to knowing nothing. What counts is what the camera can do, and that photo really does say very little about it. Only the HD decal says video, that's pretty much it and it does not say what the video functions and features will be either.
I realize there are a lot of folks who just buy blindly without checking out what the camera can do. And they might buy on the basis of a photo and no other info. But this is an advanced level camera, and people in it's target market are far more likely to go over it's functions and features thoroughly than beginners would.
Actually that does a little, so much on my to do list, which is already several lifetimes long

I agree, video, LV and such should be the differences if there is more than one model, which is not what I expect. We will get one model with no choice what's on it or not on it. So representing Sony as providing multiple models and choice is not what claimed.
I'll be surprised if all the a700 features remain on even the one model. We shall see.
