The only thing I can confirm is that Konami is working on an unnamed RPG for Wii, but hasn't specified what that title is. Personally I'm hoping it's Suikoden VI. :D Possible Bandai support with the Tales games are unknown, since they started that joint effort with Sony and the PS3/Cell agreement. :-/ I've heard Bioware is working on a DS RPG, but haven't heard anything about a Wii game from ANY western RPG developer. :( Well, the Wii has a good chance to get Jrpg's on board if Wii keeps selling like it is (3.4 to 1 ratio over PS3 for this year so far in Japan). But for some reason I think that Western RPG developers are more of the power-monger variety, and won't even look at the wii, even if the Wii does surpass the 360 in North America and Europe. :(
Nobody is crazy enough to accuse me of being sane.
