They might not even make it to 5 years for the Wii U, I know Nintendo always supports their consoles the shortest but when you design a new console you also design new games for it, which means the current WIi U owners future games are already going to be divided up, I think any new games not announced yet will quietly be moved onto the new console to come out with a stronger lineup for it. Obviously the console won't come out next year, but I'm sure by holiday 2016 they will be ready for it, especially if sales of the Wii U continue as such, what's the point of being in the console business if you make little or no money off it?
