Just an update here. Watched The Dark Knight Rises dvd last night. I played it on the xbox 360 and it looked HD. The only difference is that the top and bottom are cut out some, making it a more wide-screen picture. So I really see no point in a blu-ray player.
Probably not. When we used to use our dvd player, we had a DVD-O that upscaled to 720p for our 720p projector. That was a few thousand dollars (my Dad guys, him and his video quality.) I don't think it would be fair for the $200 console to upscale, at least not in a way that would improve image quality at all.
It's all about quality! Blue Rays are like overkill in some aspects very nice to watch. To put it into perspective DVD = watching movie in dollar theater BluRay = watching movie on opening night in an i-max theater.
