I wouldn't rule out Telefonica or Movistar or whoever they are. They left after the corporate punch-up with Repsol where Honda was the referee and Pedrosa was the prize, and pulled out of all bike racing to concentrate on that ugly guy in F1 (most people call him "Alfonso" or somthing similar), but he switched to some Vodafone job involving F1 cars and boredom, sorta giving Movistar the arse. I don't think theyre too proud to come back now.
As for Mcdonalds, well apparently they wont sponsor anyone as long as theres tobacco invoved. I wonder if that means just MotoGP, or all 3 classes?
