I went from the 20D to the 7D, but if the 60D had been available at the same time, I still would have gone to the 7D. The 60D just isn't what I want, but I think the market for such as camera is definitely there. It would be interesting to know the stats on how many 50D owners go for the 60D (or some future X0D model) and how many go to the 7D (or some future model).
