If Ferrari can give him a car next year, we will have a good battle. That's a pretty big "if" though... Vettel ignoring the team's warning on his gearing? They sound pretty urgent about it.
No no no. You have to carefully read the threads here. RB implements team orders only to help Vettel and suppress Webber, who'd otherwise be much fast.
Given that Vettel set fastest lap before being passed... If he lets Alonso/Button past, then my cynicism will fall.
I rather guess that Vettel mostly ignored the advice to short shift, explaining a) why he kept on going fast b) why the command was repeated several times and c) why the problem got worse...
