Okay, this one should stay open. 
Even though it's not exclusive, I think Final Fantasy XIII can act as a centerpiece for the rest of Square's 360 games and all the Mistwalker games. So hopefully some JRPG fans will be persuaded to take a ride on the Xbox side.
I also think it will help considerably if XIII can get a release on 360 in Japan, even a delayed release. Although Lost Odyssey will almost definitely not be the most recent Mistwalker game by the time XIII finally hits...
