Falcom and Square seem to be battling it out on release dates. Ys I&II PSP and Tactics Ogre were suppose to release same day up until Falcom announced a one week push back ealier today. I think the same will likely happen with Legend of Heroes too.
Either way PSP really is on fire the next couple of months. I hope Square is getting all these games out 1st half of this year so as to save Type 0 in the US for late summer where they usually released all their other big name PSP games in previous years.
