Recent sales numbers indicate that the breakdown of Final Fantasy XIII sales in NA and Europe combined is roughly 60% PS3 and 40% 360, which is MUCH closer than anyone expected. MS was able to pay SE enough to port FFXIII to the 360, advertise only the 360 version, AND get a bundle only for the 360. With that kind of money (this IS Microsoft we're talking about here) and a sizable user base on the 360 (one which may end up equaling the PS3 user base in size), couldn't MS pay SE to develop exclusively for the 360? 360 users clearly want FFXIII and MS could probably pay them enough to offset the money they'd lose by not developing for PS3.
