Ok im gonna make some bold predictions... none will probs turn out to be true, but hey... some of them are gonna be a little on the safe side

Ferrari - Kimi will b the title contender, probs champion? Massa let down again by reliability?
Mclaren - Kovy to spoil Lewis's title ambition by stretchin Equallity

Williams - Rosberg comes into his own - worth a punt on Monaco? Williams challenge for 3rd?
BMW - Kubica beats Heidfeld (ok that may be way out) they won't be third
Renault - Winners by the end of the season? Schumacher-esque '96 style driving by Alonso (minus the parade lap stunts) Piquet gets better as the car does?
Red Bull - Coulthard's last year? Podiums a plenty? The return of Webber's banzai qualy laps?
Toyota - Stays right where it is. Glock shows Trulli the door.
Honda - Dog of a car? Again? (hopefully not) If so, Button's last year at Honda?
Torro Rosso - Fighting for points in the early part of the season, Vettel cements his rep? and Bourdais to show his worth... like he did in Cart
Force Idea - Hopefully improve? Sutil to beat Fisi!
Super Aguri - Way way way back... Sadly Davidson replaced for financial reasons (aka pay driver)
Most of this isn't going to happen I know... but never say never lol!
