Not really, because of the fact that the XBOX 360 doesn't even seem to exist in Japan and the game doesn't sell too great in the West, the PS3 seems the natural platform to put it on. Not to mention that the game doesn't really appeal to the typical XBOX owner at all. FF13 sold roughly 3x more on the PS3 than it did on the XBOX 360, that isn't many sales at all, i reckon that if the game remained exclusive SE would have gained more sales from the fans that abandoned them, not to mention that porting the game and most likely changing its structure increases the development time even more.
In the end, a game does get a larger turnover if it goes multiplatform, but exclusives games remain exclusive because that game appeals to that certain platform.
Multiplatform games are great because everybody gets to play them, but this is an exception. When Final Fantasy XIII was announced for XBOX 360 the game structure had to be changed and then the game had to be ported causing a LOT of changes in the game and many delays. When you think about the fact that the majority of XBOX 360 owners think "WTF is dis gay Jap crap" (sadly the same case for a lot of PS3 owners too), was it really worth altering the game and delaying it to earn the same amount of money and sales if they hadn't made it multiplatform?
(And about Squaresoft jumping from Nintendo > Playstation, i totally agree, i would have hated the N64 if it wasn't for Ocarina of Time, the N64 had a rediculous limitation when it came to its cartridge capacity, Final Fantasy VII probably wouldn't have been the same, which is probably the main reason why i didn't like Final Fantasy XIII coming to the XBOX 360.)
But seriously though, death threats? It already came out in North America why would it matter if it came out in another region, sure its irritating that Square Enix lie, but its not the first time they have done that hey? Anyway Square Enix are about to make 10 Japanese people very very happy ^_^.
