I am also a big Canon guy but my loyalty extends only as far as Canon gives back. I do feel that lately Canon has been moving much slower. I have been much more excited about Sony's developments. However, I feel better equiped with my pro gear (what I rely on) coming from Canon, but my secondary camera stuff (like my travel stuff) HAS moved to Sony, particularly the NEX-7 with the Sigma 19mm lens.
My only disappointment is the lack of quality lens from Sony for the NEX line without adapters (or doesn't cost way too much for a secondary body).
I have to say, that the Sony a7R looks very intriguing and the launch lens all look great too, much better (and more expensive) than the NEX launch but seems to be a better match. I currently plan on buying a7R as a holiday gift to myself, because I of course earned it! Thats my story and I'm sticking to it.
Ironically, I like the retro look, I may get less looks from thieves hopefully.
