I think it would be a huge mistake on Nintendo's part to differentiate itself so dramatically from the other consoles, or let itself be overrun in less than a year by the likes of Neo and the Scorpio.
These numbers came out showing just how bad third-party support for the Wii U has been and why I get that the Wii was shovelware central, it still sold like hell.
If Nintendo are going to pull gamers away from Xbox and Sony, they have to at least have the majority of those system's blockbuster third-parties. Zelda and Mario aren't enough - the Wii U has proved that.
