Valentino Rossi says he will reveal on Sunday which manufacturer he will ride for in 2011. The six-time MotoGP champion is expected to switch to Ducati, following the announcement of Casey Stoner's move to Honda for next year.
Yamaha is known to want to confirm its 2011 lineup at Brno this weekend, and Rossi says he will make his plans known after the race.
"Sunday after the race you know what I will do in 2011," he told the Italian media.
The Japanese company has already stated that Ben Spies will step up to the works team next season if either Rossi or Jorge Lorenzo were to leave.
