An APS-C 7D isn't any kind of threat to the 1DX which has the absolute best of everything. People that need a 1 series camera, need a 1 series camera and an attractively spec'ed crop body isn't going to change that.
I disagree. First, you described a 1 series body with the exception of the APS-C and a 7D badge. Some sports photogs may be a little more inclined to lean towards your dream camera because of the extra reach. Some of the better off amateurs who would otherwise buy a 1D X, might go to this fictional 7D because they wouldn't have to spend as much on long lenses. Super tele primes are a little pricey. Others aren't upgrading their 1DIV's because of f/8 and the crop.
All you guys who are saying that Canon could release a body with these specs forget what just happened with the 5D. This forum almost ripped itself apart when we found out what the new 5D offered and how much they wanted for it. Nothing wrong with dreaming, just don't get your hopes up.
And thanks to stilscream for encouraging people to dig up the karma system issue again.....
Actually, in terms of specs what most are saying here so far is really reasonable. Spec some of it down a tad, a little less fps (down to maybe 8, and frankly if its a choice I'd take cleaner ISO at the 3200-6400 range over increased fps or increased native ISO). For my uses at least, I find the max fps of the current 7d to be alomost too much. I rarely set it on the highest speed because for me at least, it does not effect keeper rate, it just gives me more to go through. But then again, I'm not shooting sports.
Key factors that will separate the the 1 D line from both the 5d and 7d line is dual digic 5.
The current 7D had a launch price of $1700, so with similar stats to whats mentioned, $2-2500 is a reasonable starting point, which would give them room to launch a 70d at the $1300-1500 price point.
Direction they take it, who knows? I'm guessing it will be a case of trade offs. Kind of the like the 7D currently is, just good enough to get most things done, but lacking in just a few spots that make you want to upgrade. And for many 7D users, the 5D series is the next step, unless your a wildlife only shooter who needs the range...
