I'd like to see a digital Canonet QL17. 😀
Put a hybrid VF like the X100, but have the ability to use EOS-M lenses like the little 22/2 or whatever else they come up with. I'd like to see them release a 12mm (18mm eq) and a 47mm (75mm eq). That would give an 18, 35, 75 trio which would be really nice. The reality is probably that we'll get an EOS-M2 with articulating LCD, even less buttons (all touch screen), higher video frame rates and some crappy 18-55 power zoom lens with the same old boring 18mp APS-C sensor (which isn't a bad sensor, it's just... old).
I shoot Canon and have for years. My bag has a lot of expensive Canon equipment in it, as does my wife's. But neither of us have even raised an eyebrow at anything Canon has done lately. If they were truly smart, they would have released that 22/2 as an EF lens alongside their new little tiny Rebel camera.
The 5D-Series was/is good stuff. The 7D was a great camera but they've been slow to release a replacement. The rest are just ho-hum. Canon is taking their prominent market share and doing nothing with it because they know they don't HAVE to do anything with it. Pros will keep buying the 1D-Series. The wedding guys will keep buying the XXD-Series. The video kids will keep buying anything with 1080p and cinematic frame rates. I mean, look at what Canon did to their beloved 28/1.8. They released a 2.8 version with IS... Really!? For who? The video crowd. Canon has all but abandoned still photographers. If I wasn't booking the occasional wedding, I'd be shooting an entirely different kit. But, alas, I can't afford multiple systems and weddings pay more than snapshots of truck stops.
I hope Canon proves all of this wrong though... I really do.
