Atlus published a really bad WW2 fantasy SRPG called Operation Darkness on X360, nothing more on HD consoles. Disgaea 3 was published by NIS (Nippon Ichi of America) themselves.
Atlus mentioned that they chose the ps2 because their fanbase owned that system the most. So their next main SMT installment would be on a system which their fanbase owns the most. I believe that would be psp and then ps3, but I could be wrong. It could be the Wii, since so many people have one already.
