Alas, Sony seems uninterested in doing much with their WRC license, handled by Evolution Studios who are probably too busy working on MotorStorm 2 to put much thought into a next-gen WRC game. Thank goodness, then, for developer I-play who are working on a new WRC game. Sadly, though, it's destined only for mobile phones.
The press release for the upcoming game, included in the story, doesn't really tell anything about the game itself except that there will be two versions: a 2-D one for simpler phones and a separate 3-D one for those with more advanced cellies. The 2-D version at least will likely have a lot in common with another 2-D racer from I-play, The Fast and the Furious: Fugitive, and actually could be a good bit of fun.
