Well, I really hope for a 60D / 7D replacement that is coming soon. I like to replace my 7 year old 350D, but the 60D and the 7D are just to old (with their over 3 year old sensor). The 6D would also be an option, but it is a bit expensive, especially if I also count the new glas I would need.
CP+ at the end of the month would be a good date, then there are always the announcments in late spring, which would be the latest date I will wait for, before going with the 6D, which should be down to about 1600$ by then (comparing it to the Nikon D600 price drop).
It could be that Canon will offer something in between the 60D and the 7D, which would replace both for a while, before bringing the "real" 7D sucessor to the market. That would be fine with me, since I think the 60D is a little bit underspeced; but the 7D is already a bit on the large side.
Let's wait and see; I've been working with my 350D for seven years now, so a few month do not really matter. And even more important, I know that my pictures won't improve much only becauseI have a newer, better, more expensive camera; it's tha photographer who takes the pictures, not the camera....
