There's no chance of Stoner letting Pedrosa win just to 'get at' Rossi. I don't think Stoner really cares who finishes second and Ducati would hate to see any race win given away, particularly to a Honda rider, who would then get all the publicity/credit. Stoner has shown since winning the title taht he still wants to win every race, and win 11 on Sunday would put him level with Rossi's best in a single season. The lost money in terms of win bonuses for Ducati from its sponsors etc would also be considerable. Add to that the fact that 100 Ducati Corse staff are coming to watch the race. It won't happen.
