According to Kojima Productions creative producer Yuji Korekado, Metal Gear Rising: Revengeance isn’t being considered for a PS Vita launch.
When speaking with Eurogamer at Gamescom last week, Korekado explained, “As of now we aren’t considering a Vita version. The reason is one of the main appeals of Metal Gear Rising is this option of the free cut. That requires a lot of hardware power, which is only possible with the power of a PlayStation 3 or Xbox 360. So as of now, we haven’t contemplated bringing it to handheld consoles.”
With Sony’s Vita struggling at the moment a big release like this could have helped pick up sales. Maybe we’ll see a Vita exclusive Metal Gear game in the near future.
