Nintendo needed to change the name to Wii 2, keeping the "Wii" in the name, as it's only fitting since they use the same controllers as the Wii, rather than changing the name to something completely different. As well they needed to change the look of it as it's extremely similar to the Wii.
The Wii U sounds and looks like nothing more than an updated Wii, along with some of their games seem like its just updated (ie. NSMB, Wii Fit)
