I don't think it will be Hamilton despite the wishes of Bernie & Co.
He showed us this year that he is capable of the best (his season up until Japan) and the worst (Shanghai and Interlagos, after having 12 points to Alonso and 17 over Kimi).
I would like to see Michael Schumacher replacing Jean Todt as head of the Ferrari racing team. I am not a Ferrari fan and I wasn't a Schumacher fan, but he really was great and I think he still has a lot to offer to the sport.
And if he had Fernando Alonso on his team, that would be superb. The two best car developers working together, what more can we ask for?
Let Lewis Hamilton stay at McLaren and see what he does there.
