My Vita retail copy is still on its way to me. Not sure I'll keep it, between the lack of cross-region online, crashing issues in story mode, and godawful loading times, the game really sounds like a total trainwreck.
And with Ultimax coming up next week, getting the PS3 version instead would be futile as I will not have time to play it.
It's a real shame, really, that series just can't catch a break in the west, with the previous edition being released the day of the Great PSN Hack and all...
