Have they finally confirmed the 60D? There have been a lot of rumors of it for a while, but they've all been just that - rumors. I personally don't know how they'd place 60D price and spec-wise without cutting into sales of 7D (unless, of course, they're updating 7D as well).
As for LCD screen on 50D, it's same size as T2i, but T2i has bit more resolution (920,000 vs. 1,040,000). I personally couldn't comfortably use the Rebel-line bodies when I tried them out - too small for my hands and not having the second control wheel was annoying.
