sure. because 7D2 will bring FF features to the table as well, superior ISO on par with 1dx and overall IQ. oh yea, we must not forget more rugged body and high shutter life count. AF as well..
that will be the day
If they dropped the number of megapixels down to 5 or 6, they could have SUPERIOR ISO performance to the 1DX... but we can all guess how likely that is
With the same level of technology FF will always have 1 1/3 stops advantage over APS-C. Keep in mind the marketing people talk about Jpeg images.... I have no problems that an out-of-camera Jpeg from a brand new design with newer algorithms and more computing power (7D2) will get close to that of an older design, like a 2 year old 1DX (and it will be two years old or more by the time a 7D2 is released). BUT!!!! Take the RAW image from the 1DX and process it like the 7D2 RAW image, and your stop or so FF advantage is back. Even if they came out with great advances in technology that moved the 7D2 to 1 stop (or the almost impossible 2/3 stop) away from the 1DX, by the time the 1DX2 comes out, that same technology would restore the 1 1/3 stop advantage of FF, or if more advances have been made, make the gap wider.
And as far as shutter count life goes, don't forget that an APS-C shutter is smaller and lighter than a FF shutter. If all else was equal, it should be faster and last longer than an equivalently built FF shutter..... so yes, I CAN believe an 7D shutter that lasts as long as a 1DX shutter.
Weatherproofing? The only competition the 7D has in the Canon lineup is the 1DX, so having a 7D2 come close to a 1DX is reasonable.
FPS? The 60D and the 5D2 came out around the same time.... guess which one had more FPS? Heck, the 60D at 5.9 is almost as good as a 5D3 at 6.0....
