The makers of Gunstar Heroes and Sin & Punishment are currently creating two 3-D Wii games.
In an interview with CNET Japan, Treasure president Masato Maegawa revealed that since finishing Ikaruga for the Xbox 360 and Bangai-O Spirits for the DS they have set their sights on Wii. Currently two games are in the works, both featuring a three-dimensional presentation as opposed to Treasure's more traditional two-dimensional offerings. Maegawa also noted that both titles would take special use of the Wii remote.
No other information was provided on either title, nor when they could be expected in stores.
