Canon has been pretty watertight recently, with few leaks of any substance until days before the official announcement. I'm guessing that when the 1Ds Mk4 is annouced it wil all start to happen very quickly.
It's a shame that EF-S has been relagated as there are still so many holes in the lineup. Apart from the 17-55mm f/2.8, the 60mm f/2.8 Macro and the recent 15-85mm f/3.5-5.6, there are no other lenses for serious users. I'd have to agree that what Thom Hogan says about the Nikon DX lineup (http://www.bythom.com/state2010.htm
) applies equally (if not more so) to Canon. Yes, there are FF lenses that fill some gaps, but many of these are old and a bit sub-par (e.g. the non-L primes in the 28-35mm range) and using others leaves you with a camera bag that is heavy, expensive and a bit long for many people (e.g. the 70-200mm Ls). I guess that there are third party options, but a company with Canon's market share shouldn't need to rely on Sigma and Tamron to prop up its lens lineup.
So, lets give Canon a break and write EF-S off for a year (as it's a full frame camera refresh year); may I suggeat that in 2012-3, Canon fill out some of my wishlist: Budget - Sub $250:
EF-S 30mm f/1.8 USM (priced at under $250 -Nikon can do it, why can't Canon?!)Mid-range - $250-$499
EF-S 15mm f/2.8 USM (wide angle was what EF-S was designed for)
EF-S 22mm f/2 USM (nice compact lens/body combo for street photographers)
EF-S 50-300mm f/4-5.6 IS USM (EF 70-300mm f/4-5.6 USM IS replacement for those who can't afford the L). High-end - over $500
EF-S 50-135mm f/2.8 IS USM WS (weathersealed ala Pentax -to complement the 7D Mk2)
EF-S 15-50mm f/2.8 IS USM WS (weathersealed to complement the 7D Mk2)
EF-S 8-15mm f/? (not sure for f/4 size/weight, or f/2.8 for available light?)
In addition, I think that Canon should re-focus its crop sensor lineup to offer smaller cameras to go with these smaller lenses; the 7D is great, but (IMHO) it would be even better if it were the size of the Pentax K5.
Would this mean that some people might stay APS-C rather than go full frame? Possibly, but I think that this would be more than offset by the people who would choose the Canon system and those that are currently forced to buy third party lenses.
