The Wii U will do just fine. It's just not going to be the huge success the Wii was. They finally have the proper advertising out letting people know that the Wii U is entirely different console....not just an upgrade for the Wii. The new bundle with New Super Mario Bros. U and Super Luigi instead of NintendoLand will help as well. Super Mario 3D world will slowly increase sales as well.
It's not like Nintendo isn't going to move any systems this holiday. The $299 price will help
Nintendo made a horrible move by having none of their big guns release all year. Pikmin 3 and The Wonderdful 101 are great, but they are not system sellers. They needed to release A new Zelda (Not a remake), a Metroid, Mario Kart/Mario Party, Donkey Kong, Smash Bros, Star Fox....something. I know many of these are in development, but these are the games that people expect from Nintendo. I love my Wii U (And PS4 ;) ) but I didn't buy the Wii U to play ports and crappy third party gimmick games.
