Grasshopper Manufacture’s (makers of Killer 7 and No More heroes) CEO Goichi Suda says that they’ve done everything they can do with the Wii and that they should move on. He bore all in an interview with Edge Magazine.
"To expand NMH to new possibilities, we need a new platform. Wii is a great platform, but we've done everything we can with it now."

Project Natal seems to have caught his eye.
"We developed No More Heroes with the Wii remote in mind, but now I want to think about games with Natal in mind. I have to ask myself, as a game designer, what new games can be done with this, what can be an interesting experience and challenge, and I'm looking forward to that."
No More Heroes 2 is therefore set to be the last of the franchise to appear on the Wii and is set for an early release in 2010.
