Thanks. Considering how cheap and small it is, Nintendo could theoretically put the CPU into their next-gen console at a very low cost and use it for partial BC with the Wii U/Wii/GCN game and other things when playing its original games. They already made similar choices with the DS and 3DS. The biggest issue with Wii U compatibility would be the Gamepad. If they desperately want BC without having a controller with a screen, they could make alot of OS and Game patches to deal with most of them.
