I don’t think many people expected Red Bull to be as strong as they were this year. Look at Ferrari and McLaren in 2009- the previous year they were fighting for the Championship right up to the last race, so the following season they hadn’t had enough time to concentrate on the new car.
The main contributor to that was the wholesale change to the regulations, next year the regs are very similar so it’s likely the same teams will be on the pace again.
