There goes my hopes of getting it on GOG. :(

It will be on gog likes Rayman Origins.

You can try an emulator for Wii, if you really like this game or buy a Wii? :P

Since I'm not from Japan, I can still get it on PC via Steam or UPlay. It's most likely not coming to GOG though, since they won't sell a game if they can't sell it globally (and at the same price).

Not blaming GOG for it, since I actually support that policy. But it's still a bummer.

Dolphin is a Wii emulator; not a Wii U emulator.

he said wii, but i guess google knows more about that

I don't see why it's not going to GOG later. I mean the game is still multiplatform for the rest of the world. Ubi-Nintendo really desperate to sell both Rayman and Wii U in Japan and Ninty need all the leverage they can get.
