That seriously sucks. They could at least take the region lock off the NA release so EU players aren't left out for so long. (That said, Persona 4 Golden is getting delayed outside Japan; maybe something's up that's affecting both?)
Also, I think this was noted before, the mechanics are actually very user-friendly. Just take a short run through the Lesson Mode and you'll know the basics and then some. Overall the game is friendlier to beginners than BlazBlue and Guilty Gear.
On another note (since I finally got P3FES off the PS Store), the ending still never fails to make me cry. T__T
Finally, in other news, I've changed out my signature and avatar pictures; one is of Aigis, one of Kanji, and the last, of course, is Naoto. (In a short spin-off manga, Persona X Detective Naoto, she'd grown her hair out. Kanji is embarrassed to see a 17-year-old Naoto.)
