Any chance that Atlus could pick up Pandora's Tower?
They could, but they're not going to. This game was dead in the water in NA when XSEED announced they weren't touching it before they'd even seen the sales of The Last Story (which probably speaks volumes about how well
that game is selling as well, since it's the kind of game that would see most of its sales on pre-orders).
Plus, Atlus has a lot on their plate just supporting the handhelds right now, especially with their favorite child Persona 4 coming out on Vita in the next few months. If Pandora's Tower were going to be released in NA, it would have to hit this Fall because I don't see there being any noteworthy software being on Wii once Wii U launches. Import the game if you want it, because that's the only way you're going to be able to play it in NA barring an unprecedented and unlikely eShop release on Wii U.
