I'm not surprised, I think gamers have long since moved on from the Wii, and the main reason it's still selling is dance/fitness games

But why would that be a British phenomenon? In other countries Zelda is doing much better. 

It's underperforming everywhere, bar the US, and even then it's not spectacular numbers.
