Last night I did donate to the ML team and installed it on my T2i, I like it a lot but I don't know if it is a deal breaker that I can't have it on the new camera. The photography factor is definitely effecting my decision also though, as I have attempted to do headshots with my T2i and I feel somewhat limited, even compared to the 7D. BTW all my lenses are EF, not EF-s.
Oh yeah, and autofocus, while cool, is a zero factor because as was said earlier, no real cameraman uses autofocus. I don't think I've used autofocus while shooting video since before film school.
I appreciate all this input, right now I am definitely leaning towards waiting, maybe I'll pick up a mirrorless camera or something to keep me entertained until the new FF camera is out.
