Are we there yet?
Would the existing 7D users sell off your current 7D's after you buy the 5D3, if the AF of 5D3 can match the 7D?
Still unsure as to what my exact upgrade path will be (what will the price of the mkii be in a week vs when will the mkiii become available?) Either way, I'd be more likely to pick up a mkii use it till end of fall then sell it and grab a mkiii (or better, get the mkiii then sell the mkii).
I'm not a wildlife shooter, but I can think of many reasons to keep the 7d. As an emerging photog, I am working lots of events that don't exactly pay very well. The 7D would be what i use for those (at one event, I had half a beer get spilled on my 7d, I almost decked the guy, but instead rushed to the bartender to get a rag). Of course , the better solution would be to only work bigger better gigs. But for now, it is what it is. So the 7D would be a good backup cam to use in situations i'm not comfortable pulling the more expensive rig out. I do also shoot a lot of live musid, and the extra reach of the crop sensor is great for catching the crisp closeup of a singer or the drummer way off at the back of the stage.
I am really hoping that canon will preserve the 7d line and give it a super upgrade (imagine a pro level 7D, with 25+ MP priced at a cool $1900 for the body...)
