Disney just dropped about 20 games onto Steam. I mention this as Pure and Split/Second are two of them. Pure is a fairly awesome racer that plays rather like SSX, but with off road bikes. And Split /Second is a racing game where parts of the racetrack will explode on you and form new raceways. Sadly, they're both a little pricey at $20, but if you see them on a sale, pick them up.
Oh, and Smash for Wii U will be on November 21. Aussies? You get it two weeks later.
