The game has probably reached the point where at minimum it'd need to sell 1.5M to break even. However with their other properties not doing so well they'd probably want a minimum of 5M sales. Given the likelihood of Microsoft EDD slapping a few million down on the table for co-promotional support and the extra sales it does make sense we'll see it on the Xbox 360.
For what it's worth Nomura may care about it going multiplatform but outside of Japan I don't think he'd care quite as much and chances are the release will be delayed for regionalisation. So chances are we'll see a quick and dirty port like FFXIII which means the game will be released on a few DVDs and may have lower resolution etc on the Xbox 360, this hardly matters in the scheme of things as it never seemed to back in the last generation when such differences were actually meaningful.
Tease.
