I purchased my 7D on the first day of availability at full MSRP.
Did not regret it for a single moment. It is an amazing camera. Still love to use it today.
By now, I would happily buy a 7D Mk. II with the following improvements:
* current state of the art sensor, at least on par with Sony/Nikon sensors, especially as far as DR is concerned: +2 stops DR and +2 stops in Hi ISO, meaning, ISO 6400 behaving like ISO 1600 on 7D. And ultra-clean ISO 100.
* 18 MP are enough for me, but up to 24 MP would be fine too, since I do have lenses to match
* AF further improved, ideally in via a really fast hybrid CD-AF + in-sensor Phase-AF
* WiFi build in, GPS built in
* wireless EX-RT flash transmitter built in
* retain pop-up flash / optical master
* touch screen LCD, fully articulated!
* significantly better new generation battery packs ... with higher energy density like on Hero GoPro 3
* locking mode wheel [as on 5D III] with 4 Custom Mode Settings
* price not higher than 7D MSRP ... USD/€ 1700
That alone would make it a sure winner.
If Canon had any marketing genius working for them, they would just go ahead and bring it in two versions - DSLR AND mirrorless - with exactly the same specs, performance and functionality [except OVF vs. EVF and loss of regular phase-af on the mirrorless version] and at exactly the same price. :-)
7D Mk. II
DSLR - size, weight, shape exactly like 7D, again with 100% OVF and regular Phase-AF in addition to hybrid-AF [CD-AF+ in-sensor PD-AF ... only used in live view]
mirrorless, size, weight, shape very similar to EOS-M ... only slightly larger due to brilliant, state-of-the-art EVF. Loss of mirror-dependent Phase-AF but still 80% AF speed and performance with hybrid AF system. EF-M mount, further improved kit-lens, plus a few pancake fixed focals. All EF-S and EF-lenses fully functional via existing EOS-M adapter.
I would take the mirrorless version, because I always wanted only one camera with only one ergonomic layout to use "ultralight" for travel, mountainieering and street photography ... and to use "like a DSLR" for specific tasks, where size & weight do not matter e.g. because large lenses and/or tripod are required anyway.
Within a few months all Canon, its competitors and all of us would finally know for sure, where customers stand on DSLR vs. mirrorless.
As I said ... pure genius. :-)
