Nintendo released there financial numbers from the last few months and things aren't looking good, especially for the Wii U:
3DS sales are doing good though, which gives me some hope for Nintendo's future. I myself bought a 3DS two months ago, and was very pleased with it. I don't have a Wii U, along with just about everyone else, and I don't plan on getting on until Smash Bros. comes out. That was the reason I bought a Wii, and it might be the reason I buy a Wii U. I hope by then there are even more good Wii U games that I can get, since one game does not make a system. Good luck, Nintendo.
