Well it's funny because Nintendo putting the likes of F-Zero on the Wii U would help sell the system to me, and I'm a potential customer.
Give me an F-Zero (etc...) and then I might consider a Super Luigi, or Mario 3D World etc... it's horses for courses.
They didn't seem to have a problem giving us F-Zero, 1080, WaveRace, Doshin, Chibi Robo, Starfox, Mario Golf, Mario Tennis, Battalion Wars etc... on the Gamecube, and I thought that was a profitable console for Nintendo?
Nintendo are sat on a money pot. It wouldn't hurt them to put out some of their other franchises in order to get people buying the console, even if they aren't multi-million sellers. The current strategy clearly isn't working well anyway.
