I agree Antonio. The Santander thing made me question not whether Fernando would stay, but whether Ferrari would keep him knowing his main sponsor would probably go away. And as you say, Alonso must be sick of taking a 12th place car to close to podium positions each week just through the brute force of his driving skill. I do think he wanted to finish his career driving for Ferrari, but the team made a total hash of it. With DiMontezemelo and others gone, I think Alonso knew the writing was on the wall. I will watch with great curiosity how next season goes if he does sign with McLaren. Ron Dennis has always seemed a dodgy bastard to me and I don't see Fernando meshing any better than his last time there. I hope I'm wrong.
As for Vettel, it's going to be hard. He's bailing from Red Bull after one season of a bad car. What will he do in the next three years that it will take Ferrari to come up with a competitive car? He'll go mad. And I will have a hard time rooting for Ferrari with him in the cockpit.
The person who gets the best end of this stick in my opinion is Kvyat. I think he'll drive the wheels off the Red Bull next year and have a great season.
