This information comes from Ubisoft’s Michel Ancel, who was asked if believes Wii U is a next-generation machine…
“Not really. I think Wii U is next-gen in terms of interface. I think people are going to copy it, because you’ve got this mix between tablet, touch screen and big screen – big screen and little screen – there are a lot of possibilities. I don’t know if Sony will do it, or Microsoft – but yes, I think it’s a possibility. But I think the main thing is to have this – offering new ways to play is very interesting.”
As you can see above, Ancel didn’t exactly explain why he doesn’t view Wii U as a next-gen console. He seems to believe that the interface is, but not the console as a whole? I wonder why…
