I might have to get a 2nd Wii U at some point to play new games, unless of course like the Wii, Wii U disc updates can be blocked.
But all my games are on the first Wii U. If I bought a 2nd Wii U for game hacking and stuff, I wouldn't be able to use it until there was full on piracy. I'm not going to buy a 2nd cope of 3D World or anything else just to hack it.
