I don't know for you, but Mario Kart is as strong as ever. With 22 million games sold worldwide (and the 19 million from the DS), this is one of the biggest racing game ever, with Gran Turismo following in second. GT is pretty big too.
I think the industry lacks BIG racing games. I mean, there weren't that much hype around Blur and all Need For Speed spinoffs. They just lack polishing like they used to have before, unlike Mario Kart and Gran Turismo.
