You know.. With my style of shooting, and for my needs.. I'd be perfectly happy with a 22mp 5D MKIII if it meant keeping my glass. As long as there was a notable improvement in IQ, count me in. I'm not in the position you guys are in though.. I went from a Rebel XT to a 7D. I'll be thrilled to get my hands on whatever new full frame body I can. I don't really crop at all these days, I can see how important it can be for bird photography, just doesn't have that much of an impact on me.
Also, still trying to wrap my head around the perceived noise due to higher resolution concept. Expect a new thread with me pleading for you guys to pick up the threads of my constipated thoughts and questions. heh. :P
