Kimi and Ferrari will win in Melbourne, probably with a 1-2. One of the McLarens will be third.
After that, it gets interesting: I'm hoping for good things from Williams, and I think (hope) that the scrap for 4th/5th through to about 10th will be well fought out between Williams, Renault, BMW and Red Bull. Then Toro Rosso and Toyota, then Force India, and Super Aguri - assuming they're still around - will be last

.
I think the field is broadly the same as last year, but the midfield (behind the top 2) should be closer. I reckon Ferrari will dominate, unfortunately - as I said last year, I'd rather see a close season that my prefered driver doesn't win (which is exactly what we got) than have 1 team dominating, whoever that team is. If Kimi doesn't win the title next year, then he's got some serious explaining to do - Alonso's in a midfield car, and McLaren has had a turbulant time recently - regardless of what their PR department say - and I don't think the Hamilton/Kovalainen combo have the experience to take the fight to Ferrari.
Edit: I forgot Honda, but I think that's likely to happen this season anyway.
