Nintendo has let out a flood gate of new information about their new console coming out this fall.
The WiiU will be out by November 18, 2012, and comes in two bundles. There is a standard version that comes with the console, the WiiU gamepad, 8GB of memory, AC Adapter, sensor bar, and a HDMI cable, for $299.
The Deluxe bundle comes at $349, and includes all the above, with an upgrade to 32GB of memory, a WiiU Gamepad charging dock, a membership pass for something called the Deluxe Digital Promotion which gives discounts for digital products till 2014, and the pack in game Nintendo Land.
You may have noticed that they do not include any Wii Remotes with any of the bundles as the console will be compatible with existing remotes, but the catch is that they have to be Wii Remote Plus or have the Motion Plus attachment. Additional Wii U gamepads costs are also currently unknown and whether the console will support a second one is a mystery at the moment. The Wii U does have backwards compatibility with Wii games, but Gamecube games are not so keep your Wii's or Gamecube's around.
They've announced that Nintendo Land and New Super Mario Bros. U will be launch titles alongside the console but no news on what else may be released day one. They have confirmed that there will be 50 games within the launch window of November 18 through March 31. Some notable releases in that window include Pikmin 3, ZombiiU, Wonderful 101( aka Project 100), Assassins Creed III, Mass Effect 3, Wii Fit U and much more. There's a complete listing here from Kotaku.
Some big third parties have announced exclusive future titles for the
Wii U like Xenoblade developer Monolith Soft. Capcom has announced
Monster Hunter 3 Ultimate exclusively for Wii U as well as a 3DS
version. And surprisingly, Platinum Games announced Bayonetta 2 as a
Wii U exclusive and will be published by Nintendo. Koei also announced a port of Warriors Orochi 3.
There aren't any dates for these games in the US yet, but Warriors
Orochi 3 and Monster Hunter 3 Ultimate will be release titles in Japan.
Monster Hunter 3 Ultimate will also be bundled together with the
console in Japan only.
There's also something like a social network for the WiiU called the MiiVerse. No details on how that functions yet to my knowledge. The cost of a Wii U game is also currently unknown but I would like to assume they will cost $60 now like everything else, especially if they consider the Wii U's hardware to be comparable to a Xbox 360 or PS3.
EDIT: Looks like I was right with the $60 price tag of Wii U games. All games will retail for $59.99.
