Big megapixels talk's gone quiet; delays to megabucks lenses... To be honest, other than reputation, this is probably not of much concern to most Canon users, even more so if the hi-res camera is going to be a 1-series. What do Canon need to do to please most users?
1. Re-establish faith in their core enthusiast market, i.e. APS-C DSLRs (sales figures don't lie, as Neuro likes to point out). How? EF-S 15mm f/2; EF-S 22mm f/2; EF-S 30mm f/1.8 would be a darn good start! A 70D and a 7D MkII in 2013 are also a requirement (yes, I think there is still a need for two separate models)
2. Next generation of APS-C sensors - we want to see progress: less noise, both at high ISO and in the shadows.
3. Show commitment to EF-M: enthusiast orientated body with EVF; faster AF; lenses - see point 1 (above)+ 60mm f/2, 85mm f/2 and 55-200mm zoom - credit to Canon for the EF-M f/2, assuming performance is up to snuff.
4. A more compact large sensor enthusiasts'... well, compact!
Or maybe Canon thinks that everyone will shell out for full frame DSLRs if they spread enough FUD about APS-C's future? Either that, or a lot of people will be taking a serious look at the likes of the OMD EM-5, XE-1 or NEX-6/7 (notice that I've omitted Nikon from that list?).
Canon's got a lot to prove to their average users (the ones that are least tied in with lens purchases) in 2013.
