How about Disney demands the game reach every possible player? And they didn't do it last gen since Square had an exclusivity deal with Sony at the time the first game came out (a subsidiary had to be set up just to make Crystal Chronicles), and the PS2 was the overwhelming leader by the time the second game came out.
This gen is more even, and S-E even stated they will not support one system over another.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
