Alright, I'll add my $.02.
I personally HATE the idea of a swivel screen on a semi-pro/pro camera body. It simply presents too many issues with durability. I mean, those cameras are all metal, weather sealed, just built to take abuse. Adding a flimsy articulating screen just seems stupid to me. The only upside I see is that they can be flipped around for safe storage/travel, but really, when is the last time your screen got messed up in your bag?
I would NEVER buy a dslr with an articulating screen, especially one of that caliber.
I tend to think Nikon agrees with this logic, because the D7000 came with a fixed screen. They could have easily added one to better match up with a 60d spec, but they didn't, and I'm glad.
