AWESOME!!! Hopefully soon this article will be updated to say ditto for North America. I already own BOTH the Wii and New 3DS versions of Xenoblade, but it's my all time favorite game so I wouldn't hesitate to download it TODAY.
As for the special editions...I regret not pre-ordering and getting the art on the Wii, but honestly I hadn't heard of the game so I didn't know any better I learned about it through listening to the back catalog of Radio Free Nintendo.
If the Wii U Bundle has a decorated Gamepad like the Wind Waker did I'll proably buy a new Wii U to get it, if not I'll get the game with the steel book and the posters.
