When last asked about the Wii U version of Metal Gear Rising: Revengeance, Kojima Productions said no chance as they believed that Wii U’s Game-Pad was not even a proper controller. This is what the Producer Yuji Korekado had to say back then:
One of the strongest appeals of the Wii U is the GamePad. However, we’ve constructed Metal Gear Rising so you can fully enjoy the game on the controllers whether it’s on the PS3 or the Xbox. So, currently we aren’t thinking about Metal Gear Rising on the Wii U.
Well, now Platinum Games writer / translator JP Kellam may have given some hope to Nintendo fans regarding Metal Gear Rising: Revengeance on the Wii U. When replying to a fan inquiry about the game and its status on the Wii U, this is what he had to say:
[Konami] would have to see demand for it and bring us the request to port.
This means that Konmai has the final say in this matter. However, I’m sure Platinum Games won’t mind working on the Wii U version of the game as they already are working on 2 Wii U exclusives already.
