Listen up Canon DSLR R&D team! How about genuine 500th sync for the 7DII? I'll personally visit Japan and give each one of you a big hug.
What sync speed will it take to keep you away from us? Just kidding.
While I've been saying for a while that a 7D2 will appear and will be technically stunning, something that will even more formalize the APS-C as a foundational block of the Canon catalog, the 6D abortion is making me wonder if Canon has simply lost their way. Given where they seem to be going, maybe a new 7D2 will also order airline tickets for me.
Anyway, to answer the question, I'd want a 7D2 to be the APS-C equivalent of the 1Dx. It should have a new sensor that can match what Sony is apparently now doing with sensors. I wouldn't mind if it dropped to 16MP if needed to do this. Truth is, that's big enough for anything anyone needs to do with this camera. (How many cropped down 20 X 30 bird prints are people really going to make?) As I've said before I want ISO 100 to give me the same performance I got with film at ASA 25, maybe 50.
What I surely don't want are non-photographic geegaws -- like this GPS and wifi they soiled the 6D with. If you want those things, get the accessories that make them happen and stop asking me to pay for your features. They also don't need to make the 7D2 any great shakes in the video department. The aspiring Spielbergs who want that should be moving to FF where the options are plenty good. I accept they have painted themselves into the corner where video is now mandatory, but it can be just the basics.
I've also said in the past the price for the right 7D2 product will be in the $3K range. I'm more convinced of that seeing Canon's recent pricing practices.
Thanks for asking -- and be careful around those Japanese engineers. The one's I've known weren't much for hugging. A good bow will be plenty!
