Tripe ...
Button will 100% resign for Mclaren for the 2012 season
This. Mclaren have an option for 2012 and IMO they'd be bat**** crazy to even contemplate anyone else. I suspect button will be insistent on a wage increase which I think McLaren will be happy to pay as well. There was a suspicion that Jenson was immensely flattered by the Brawn in 2009 which was why his wages were lower than you'd expect for a World Champion as well as the fact he really wanted to drive for them so didn't push so hard on the money front. Any suspicion that Jenson was gifted the WDC by the car should be well and truly laid to rest with his performances this season. he will sign, probably for two years at least.
With regard to Red bull I suspect Christian Horner has looked at the Torro Rosso drivers and while they appear good enough for TR they are nowhere near what Red Bull would expect so he's signed Webber for another season. i can't see Buemi or Alguersari EVER driving for Red Bull. TBH i'd expect very little movement over the next couple of seasons until Webber retires and then we might see some changes.
Red Bull:
Vettel: Won't leave. EVER unless they create two years or rubbish cars. unlikely!)
Webber: Maybe has another year after 2012 but not much more than that.
Ferrari:
Alonso has a multi year deal and I suspect will retire before driving for anyone else
Massa is a difficult one. Obviously well liked at Maranello but needs to improve. Possibility of massa for 2012 then Perez from Sauber.
Mclaren:
Hamilton: multi year contract, doubt he'd leave to go anywhere TBH
Button: Will sign for another 2-3 years I think.
Lotus Renault:
Petrov (has done well and brings sponsorship)
Kubica/Senna if bruno continues to impress.
Mercedes:
Schuey will complete his three year deal
Rosberg will also stay i think.
Di Resta to take Schuey's place for 2013
Force India areharder to call:
Sutil has consistently failed to impress
Di Resta will stay for 2012 then move to Mercedes
Sauber:
Perez (a Ferrari young driver remember) has signed for 2012, then to Ferrari
Kobayashi has also signed for 2012. Would love to see him get a chance at a top team, maybe Mclaren in 2014?
Torro Rosso:
Buemi and Alguersari are more difficult to call. have done quite well recently but still prone to errors. I suspect Ricciardo will have one of the seats if not next year then in 2013.
Lotus:
Will continue to improve. i don't think they could improve on Trulli and Kovalienen. both experienced drivers who have raced top cars so know how to develop the car.
Virgin:
Really haven't a clue. Wouldn;t be surprised to see them drop out or get bought out at some point.
HRT:
Will bow out after this season I reckon.
