Canon is acting quite a bit like Kodak lately.
Unable to innovate, don't want to innovate, stubborn, hard-headed, doesn't listen to customers/users?
So the new AF in the 5D3 is not listening to Canon 5D2 owners??
So IS becoming standard on even short-focal length primes as well as the new 24-70 standard zoom is not listening to customers??
Canon is listening to customers, they're just not listening to the vocal minority 
Who asked for IS on short-focal length primes. If anything I'd say most people wanted internal zoom and IS on the 24-70. I still bought one anyway.
Honestly the DR thing nobody really wasn't even on most people's radar until the D800 came out so I can forgive them on that.
What I would be interested in is a new
14-24
updated zoom: 16-35 L II
updated primes 35, 50 (1.2L or 1.4) and 85 mm L lenses
make 5D/1D series bodies all have WiFi/GPS/ Radio Flash Trigger built in
stop crippling video output
prices that are not out of whack
In the Future a high MP high DR sensor.
The last thing that got me really excited was the 200-400 1.4TC lens which I would like to own someday.
