The Metal Gear Rising making of video that debuted yesterday showed the game being controlled via an Xbox 360 controller, prompting some speculation that Xbox 360 is the game's lead platform -- that is, Platinum Games is developing the game first on Xbox 360. This is not the case, according to Atsushi Inaba, producer on the Platinum side of the collaboration.
Inaba clarified the situation today via Twitter. For Bayonetta, Platinum developed only the Xbox 360 version. The PS3 version was handled externally. However, starting with Vanquish, Platinum has been handling both the PS3 and Xbox 360 versions of their games. Games are developed on an internal Platinum-developed engine, and PS3 is always the lead platform. However, the specs remain the same between the two versions.
The reason we saw Xbox 360 controllers in the making-of video is because that's what they use to control the game on the PC they use for cross platform development. The Xbox 360 controller is the only official option here. Inaba said that it would be nice if someone would make an official PS3 solution as well.
"So, in closing, Metal Gear Rising's lead platform is also PlayStation 3," finished Inaba's series of Tweets on the matter.
