I believe it’s probably more of a profit issue. This is going to be Nintendo’s first time going into HD so I wouldn’t be surprised at all if they decided to pull the hot new thing that’s been going on and port GC and Wii titles to the system in ‘STUNNING’ high def and make some extra money in the process. It’s easily been shown that it can be done on PC and while the system isn’t perfect Nintendo could easily look at what Dolphin is doing and use their know how to tweek it and make it work for WiiU with not much hassle…the fact that they’re NOT doing this leads me to believe that they’re going to do what I just said.
Or again they could just not do that and decide to not try to make money off of that because it’s Nintendo lol.
