I recently ordered an Epson TW1000 which is 1080p an thats the PS3 max resolution, so it should be amazing for Blu Rays and any 1080p games (like Ridge Race)
However, since most games are and will be (for a long time to come) 720p, a good 720 projector is also a good choice.
Im sure it will be amazing once its all hooked up! Cant wait to actually get it!
