I think Massa will retain his seat because Vettel is coming in 2014 so it is only a one-year seat for whoever takes it. Almost all the drivers want a Ferrari seat---but a one year in-and-out is not at all what drivers are looking for.
Vettel would be a fool to leave RB. The big red bull will spend whatever it takes and the Prancing Horse has been at the FIA bitching about the cost of racing. I guess signs of the Italian economy.
Can you believe it? The Ferrari bunch complaining about the cost of racing after they were leaders of the superteam status of the Shumey years???? Sheese, this is the biggest of the big boy racing so put on their big boy diapers and either do it or go back to Maranello.
Same thing goes for NASCAR and IRL, pay the price of admission or go home. I would rather watch 14 world class cars race than 24 crapwagons.
