With the recent announcement of the Wii U
at E3 there has been some confusion as to the rather novel tablet/main controller. We already knew that you can connect all of your original Wii hardware, specifically Wii Remotes and the like, to Nintendo's next-gen console, but it was a bit ambiguous as to how many of the tablet-like controllers could be purchased and used on a single console.
According to an article at next-gen.biz
, you will not be able to purchase the newfangled Wii U controller separately. This means that Wii U owners will be limited to local multiplayer by supplementing the tablet-style controller with Wii Remotes. The jury is still out on whether Wii U owners can synchronise their controllers to other Wii U consoles. But even if this is possible, at $600 for a new console, that’s one hell of a mark-up if you only wanted a second controller.
