I'm excited. I loved TR: Legend. It was the first great TR game in a long while. It was just too short and too linear.
I own TR: Legend on PS2, but I've wanted the 360 version also because its graphics are much, much better. However, I have some issues with purchasing the same game twice, so I'll just wait for Anniversary to come to the 360, which it most likely will, even though it's not yet officially announced. As we all know, hardly anything remains exclusive for long.
