Wii U being region-locked isn't at all without precedent
There's always much to do when it's discovered that some game system or another isn't region-free. The recent "revelation" that Wii U will also be region-locked has drawn no small amount of ire from the perpetual justice-seekers of the world who seem to think that such a move is without precedent. Of course, what's more uncommon is indeed a system that happens to be region-free by default. And wouldn't ya know it, literally every single home console from Nintendo has been region-locked in one way or another.
