garyknrd: Well they forgot about the birders for sure. With this it pretty much kills my hopes for a new high end crop sensor. I WILL NEVER BUY THE MK III period. I am going back to Pentax if they come up with a good new crop body. I kept my Sigma 500mm f4.5 lens and 300mm f2.8. Look's like and I cannot believe I am saying this. Canon 500 and 300 will be shelved until they come out with something.
Typo, my sitmake!

I'm not convinced of the so called tele-advantage of an APS-C sensor.
I transitioned from a 7D to 5DII quite a while ago to never go back. Full frame does simply offer you another kind of image. The shallower depth of field enables you to isolate your subject a lot better from the background, the SNR is a lot better and there is still plenty of detail. While your lenses have no "built-in" 1,6 TC, you have more exposure headroom (slower shutter speeds due to the "shorter" lenses and images with less noise).
You can still crop while post-processing.
On APS-C, the sensor challenges the lenses in resolution anyway. At the center, the px spread is better on FF.
Not to mention,The 7D(a lemon?) I owned had a severe banding issue, with artefacts visible in shadows even at base ISO when pulling up the exposure in ACR. While I had noticed this before, I didn't bother too much, but as my current camera does not have this problem at all, it just hit me how much better the SNR is on a FF sensor.
Breen: It is quite nice update from Canon, however.. The company became a copycat.
HDR, multi noise reduction, handheld night scene.. all copied from Sony's DSLR. Sony has HDR's since 2009, MNR, HNS also for about 2-3 years..
And now, another Canon's "breakthrough" in photography.
Ehem... What company became a copycat?
As far as I know, Canon came up with translucent mirror technology as early as 1965 with the Canon Pellix (http://en.wikipedia.org/wiki/Canon_Pellix), but stepped away from it in the early nineties.
A semi-translucent mirror has lots of advantages, but is very prone to dirt and you lose a 1/3 stop of light.
It's quite common that technologies found from competing products are adapted, modified and eventually implemented in a new format. It occured with CCD and CMOS sensors, TTL, AF and other technologies.
