Some people are very confused. Optical storage DOES NOT improve your game or graphics in any way whatsoever. It is simply a means to deliver the data. A huge game could come in 5 DVDs or in 1 blu-ray or be downloaded or whatever. The way the data is delivered is irrelevant to the game's quality. Also, running games directly from optical storage, wether its blu-ray or dvd, is pathetic. Compare to HDD/SSD, optical drives are loud, slow and more prone to fail eventually. All games should be installed on the hard drive, in their entirety, before play. Optical drive should be inactive during gameplay. X360 offered such a feature on a system level, PS3 didn't.
Blu-ray was awesome for movie playback, and for convenience. It didn't improve the games in any way.
