Oh, look, it's good ol' Paul in [CR] dream land :-> (no, really, I think your posts are among the most valuable here):
- feature set, such as GPS, wireless, remote flash control
... my 2ct: built-in rt controller
won't happen unless Yongnuo has a built-in radio speedlite system (not yet) and even then Canon would have to forced at gunpoint to give up $500 sales for a 600rt as a master. The idea is that enthusiasts are ok with optical fallback control via the pop up flash, and if you venture further into flash photography you just have to cough up the $$$ to be able to use the nice 600rt display or the in-camera rt control rather than some awkward 3rd party external controller.
I also don't see gps
in a pro/sturdy body, of course it could be done but it's rather an amateur feature given the advantages of external loggers and Canon would admit they'd just left out the 6d flash and gps from the 70d for marketing and no real tech reason.
- as the 70D has the 7D's AF, the 7DmkII will have improvements in that space
... not quite, this is a spec sheet fallacy: the 70d af system
has just the same number of af points
, knowing Canon I doubt they'll confuse simple xxd customers with too much customization in the fw plus lacking a dedicated af processor it might well be the 70d is slower & has worse tracking than the 7d1!
- an articulated screen (the 7D's is 'fixed')
... but that would half the number of potential 7d2 customers after years of dogmatism that a swivel screen
isn't "pro", cannot be properly sealed and will break off the camera just by looking at it :-> ... as a 60d owner though, I know how handy that is for video, tripod & awkward angles.
