Who says Sony paid SE anything in Japan?
Maybe it's PS3 exclusive in Japan for time constraint purposes?
Maybe they want it out this year, and making the game available on both platforms at launch might not make it happen, so they stuck with the platform that they already were developing for for Japan.
I'm not saying that they didn't pay, but seeing as the game was in development, it makes it kind of hard to believe that they had an agreement for exclusivity, and SE decided to break that, and make Sony pay.
But what do I know...
