... the days of the mirror-flipping high fps beast seem to be almost over.
Marsu, don't tell me you're buying into the mirrorless hype.
Canon's delaying strategy worked on me and I bit the bullet last fall with a 5DIII. But, I'm still interested in a 7D II.
I think my list is pretty modest.
5DIII style autofocus
Dual card slots (one each)
600 RT settings through the menu (that's a certainty)
Modest improvement in sensor, particularly in reduced noise
If higher megapixels, no loss in image quality
Weather sealing at least to 5DIII standards
Same basic controls as 5DIII
Frame Rate equal to or better than current 7D
Basically, I want a second body that I can shoot birds and wildlife with when I'm distance limited and know I'll need to crop a significant portion of the frame away.
