Valentino Rossi looks like having some serious competition from Casey Stoner, but it's not Stoner or Ducati's year yet. Rossi for the win. Having said that, after the fluke of Hayden taking the number one plate last year, anything is possible.
Also this year should finally see victories from Edwards and Hopkins, which is good news for you Yanks, and maybe even a Kawasaki podium or two. Still, you can't write off the ex-250 champs like Capirossi and Pedrosa.
In SBK, It looks like Toseland is truly on form, and Max Biaggi is at the sharp end, but with a crowd like Bayliss, Corser, Haga, Kagayama, and a handful of local wild cards, he looks like having a true baptism of fire.
Oh, you were talking about cars? All the cool kids have moved to supporting motorbike racing instead.
