Blue Storm was a bit disappointing for me, but I remember myself spending countless hours with Wave Race 64. Such an amazing game.
A new Wave Race with online play, next-gen graphics and awesome, physics-based gameplay, would be amazing.
I really want a racing game by Monster Games at launch. It'd be nice if it were a new wave race, but I'd settle for another excite game too. They put out pilot wings last year though so unless they've been working on a wii u launch title at the same time, I'm not sure if we'll see anything from them this year. It's definitely possible though.
