I've got my Wii U connected via ethernet already, so if they release the app in the UK, that's all i'll need.

If one has a Wii U already, it seems weird that one would buy the 3DS version... But I suppose portability is important for some people and buying both versions is expensive, so it would be a good app to have if possible.

I still can't decide which version to get. I'm thinking possibly the Wii U version unless I can get some real life friends who are definitely going to be playing it. I would prefer to play with real life friends than online randoms because online randoms aren't kind.
