Dissidia: Final Fantasy may end up being the biggest release on the PSP in North America for 2009. Square Enix is taking advantage of the pre-release hype by offering bonuses for those who preorder the game early.
Today, they announced that fans who reserve the game at Best Buy will be receiving the Dissidia: Final Fantasy desktop 16-month calendar for 2009-2010.

Late last week, Square Enix announced preorder bonuses for GameStop (two special edition slip-covers) and Amazon (mini-soundtrack for Dissidia: Final Fantasy). It looks like fans will have plenty of nice options when deciding where to buy the game from.
