It's definitely more likely that Vettel will go to Ferrari; after all they pay the most on the grid! Do drivers really go to Ferrari for the Marque or the money? I think the later!
One year's pay at Ferrari is one career's pay at another F1 team. Or we could both be completely wrong and they just really really dig the way they look in red overalls.
You mean, they actually get paid to drive those Ferraris??!!

There is genuinely a lot of history and passion with Ferrari, why did Alonso learn Italian (of course its possible he just learnt it incidentally), plus their a good bet to produce championship winning cars.
Alonso spent some time racing karts in Italy, probably learnt it then. He also knows french, i have heard him speak often in French during the Michelin times...
I'm sure Alonso went to Ferrari because after Mclaren, there was only one place left to go. he tried going before, but there was something about Jean Todt and so on... so he went to Mclaren. Who knows.
If it were me, i'd go just for the overalls. And the food.
i bet Ferrari's cooking service is the best of the paddock

Came out fighting indeed.
