Why can't MGS, FF, GT sell as much on PS3 as they did on PS2??

Well, MGS4 has had much better sales than I expected.  So I don't see why FFXIII won't.  In fact, I think there is a large crowd waiting for a killer JRPG on the ps3.  And by the time it actually releases, I'd expect the ps3 to cost around $299.  But I just don't think GT5 will do as well as past games...just too many racers now days.
