MS paid butt loads of money for Star ocean, so it will stay there.
Sony didn't pay much money, if any, for FF13. That was going to them simply because it was. Then PS3 didn't take off as well as sony and se had hoped. This left SE in a very difficult position.
The game is clearly a much better seller in Japan. But, since only the Wii has really taken off there and FF13 is way too far in dev to be retooled for the Wii, they had to try the only other option they had to ensure the recoup all costs and make some profit on the game. Thus, porting to the 360 was the best option.
I'm still very surprised that MGS4 stayed exclusive.
