In comparison to Xbox where it was supported till 2007 after the Xbox360 was released, this is a pretty damn short time to cut the plug on a console's internet services, but why would they support a pretty much dead console since there is a new one out already? The Wii U has a perfect Wii emulator. All the Wii U is missing is the GameCube controller ports, but i bet that the GameCube controllers can be replaced with the Pro controller or the classic one. I sure hope EA doesn't cut the multiplayer mode from BF3 any time soon when BF4 comes out.
You should post stuff like this to the Nintendo Megathread.
