In a recent interview Valve's CEO and co-founder Gabe Newell had this to say about the Wii U:
"Wii U seems to be a lot more powerful than the previous generation," he told Joystiq. "It sort of fits better into the scalability in terms of graphics performance and CPU performance, so I think it'll be a lot easier for us to fit it into our scalability model." Valve has yet to release any of its games on a Nintendo console, though Gabe told us, "We've always loved Nintendo."
This is really great news for Nintendo fans. Valve is one of the best game companies in the world and are behind the ever popular video game download client "Steam". A relationship between Nintendo and Valve has never happened before so it can only be a good thing.
