Mariokart is what gaming is all about and this looks so beautiful. I'd be very surprised if this doesn't take wii u console sales up a notch and enable Nintendo to have a pretty respectable christmas in console sales.
I already have a wii u and will definitely be buying this game unless the final reviews are actually low. I really can't see that happening though. I shall buy shortly after launch when I see the first offer price or chance to use vouchers to get the price down. I'd be looking to pay somewhere between £25-30.
