In an interview with the Official Nintendo Magazine, Bethesda’s VP of Marketing, Pete Hines, said that Skyrim on Wii U is a possibility. Here is the direct quote:

“It’s definitely a possibility for the future. We’ll look at any platform that will support that games we’re trying to make, but that’s the key thing – the console has to support the game as it is designed.”

For now, let’s hope for the best. After all, Skyrim did get Paul Gale Network’s award for Best RPG and Best PC Game of E3 2011…so it definitely is a welcomed addition for any home console to have.
