Final Fantasy 13 release on xbox 360 will backfire on microsoft !!

Why does everyone always assume the PS3 games to jump ship and go Multi? If sales was ACTUALLY the issue, would it not make sense to make all of SE's games go MultiPlat? That Includes SO4 and Infinite Undiscoveries as well. These two are so far, exclusive to 360 yet no one says "if FFXIII does well on PS3 then all those previously stated titles will go multi as well. If by some ludacris chance FF versus XIII goes multi shouldn't SO4 and IU go as well?

Blatently biased sense of justice....
