-ps3 comes with a next generation disc format (blu ray-50 gigs, xbox 360 and 360 elite are only compatable with 7 GB DVDs for games, and if you're willing to pay an extra $200 you can watch ONLY movies on hd dvd,which can only hold 30 GB)

Tons of ps3 games are being released this year. Over 40 of them are exclusive for just and only ps3, and over 200 shared titles.
Oh, and by the way, blu ray is needed, a regular dvd (which xbox 360 elite uses) can only hold up to 9 GB, whereas the ps3 has blu ray (which holds 50 GB) which means, the ps3 has much more space to hold graphic games, such as Resistance Fal of Man, it took 16 GB, that's almost twice the space on a regular DVD, for Resistance, which graphics aren't that great compared to games to come. Games WILL need more space. Blu ray IS needed.
