KGB - If you honestly believe the RSX is more powerful than Xenos by now then you seriously need help.
Mike you can coat it anyway you like it but the 360 DVD drive will still stream data quicker than the PS3, the difference is it doesn't need to constantly stream to a cache file on the HDD to keep performance up. Stop spinning a slight weakness of the older Bluray technology as some sort of benefit and stick to what the technology does actually bring properly as a positive. I swear you spread more FUD on here than anybody else.
@pitzy272 - FFXIII will be on 3 disks. Many Blurays that use up so much data on the PS3 use a lot of duplicated data to lower seek times for data across the disk so they aren't using as much capacity as you think for most game data. Uncharted 2 would almost certainly fit on 2 DVD's imo if it was actually possible on the 360 (not even going down that route of conversation).
