Vettel rules!
I expect Vettel, Hamilton and Alonso close. Schumi as well when the car is good enough, which is difficult to say right now. Button could do well with the new strategy as there is no refueling anymore and he is a very "round" driver taking care of his tires. (where Hamilton and Alonso have a much more aggresive style)
It is a long time ago that I was looking so much forward to the start of a season F1!
