I´m sure they won´t leave to play all 410 games (or whatever number is) in the Wii U.
Why? Because they only announced to pay $1 and $1.5 tax if you has already games downloaded but they didn´t say about Commodore, Genesis, Master System, N64, Neo Geo, Turbografx and Turbografx CD taxes to update your game in the Wii U.
And i´m very sure they can´t do miiverse and ask to pay $1.5 for games like Sim City, DKC 1,2 and 3 or games like R-Type (master system and turbografx), Super R-Type or Bloody Wolf, Legend of Hero Tonma, Ninja Spirit, etc, etc. So that games will be locked only in Wii mode.
Fighting games like SSFII or Neo Geo games could be perfect with online and miiverse but i´m sure they won´t update the games.
Another sad thing the Balloon Fight game has worst image quality in Wii U than Wii.


As is the green monochrome look basically crushes a lot of detail....Boggles the mind why they'd let crap like this slide and not even bother taking that little itty bit of time to fix it.
