Can the Wii U lure back the casual audience that Nintendo has lost?

[Soundwave]

They can get some back, but it will never be like it was in 2006-2008 when no one had ever seen a concept like motion gaming, fitness gaming, a wand controller, etc.

That was also before the tablet/smartphone boom which has quite frankly changed the way people interface with computer entertainment devices period, and by extension changed what people expect from a product to keep their attention.
