If people knew if FFXIII and the others were coming out on the Xbox 360 there would be a big flaming stickied thread in gen ff with people freaking out about it.
Sony at the very least, has lost some money fixing/replacing broken PS2s that were within the warrenty, since it seems to be a lot more frequent that anything I've heard about the PSX. They will probably take more care with the PS3 so it won't have that type of reputation this time around, the same way they're trying to make sure it has the best graphics and hardware capibilites since the PS2 was lacking compared to Xbox (And GC?)

You have over a year before you can even chose between buying a PS3 and Xbox 360, maybe you're jumping the gun a bit right now.
