Unless either Sony / MS come out with a cheap console coupled with a real system seller (and not prettier 7th gen games), Nintendo doesn't have to worry about them, because they'll be starting off very slow. Just focus on adding value to the Wii U, forget the competition, right now it isn't worth $300 because it has no games, a bleak future (3rd party support), with better alternatives available on the market (PS3 / 360).
Another Mario Kart, Smash Bros, Wii Fit will help, but it won't get them out of the shit they're in. They need something new. Unfortunately I think they've been out of ideas for a while now, so it's looking like a Gamecube repeat this gen.
