My room is 12.5'x24' with ceiling height of 81" and I have a 10' wide 2.40screen seating about 10' back. I think the image is just right for the room. Of course always wish for a bigger room and bigger screen but thats not changing anytime soon.
PS3 will be 3D but only 720P due to limit in bandwidth with audio as well HDMI 1.3 can only carry so much. Some players are using a dual output one for audio one for video to do full 1080P. The projector will require a player like that.
