Ok, quick opinion here, I think that Ferrari will blow out of the gate next year, because of 1. Their drivers, and 2. The fact that they gave up and last years car very early.
I don't know about that - they didn't make the leaps and bounds with the F60 the way McLaren did when their car. If you look at Raikkonen's results from Belgium onwards, he's all over the place: two podiums, two points finishes and two non-scores. The F60 was only good under certain conditions, whereas the McLaren was the strongest car on the grid. Ferrari would normally go back to their 2008 car and build from that since it was a good platform, but the new regulations for 2009 meant the F2008 is useless for collecting data.
They're Ferrari, so they'll no doubt be strong ... but they're not in a very good position to begin with.
To be honest, I'll be happy if Lotus go with any of their old liveries, even the early 90s liveries were quite nice.
What if they did a black one with sponsors in gold? It wouldn't be John Player Special, of course (do they ever exist any more?), but it could be devastatingly good. And at the same time, reviled by people who think Lotus have no claim to the Lotus name.
The only teams that are probably going to change their liveries for certain will be Brawn and Renault, both becuase they'll be getting new spsonors. I hope that Brawn keep the white, black and yellow - or at least the black and yellow - in some way. I like that they have team colours.
Manor have traditionally run in black (I think), so that will probably be their main colour. I doubt Ferrari will be overly thrilled with them if they want to run a red one because of Virgin, so I could see the team running black with red highlights.
Campos are probably going to have light blue if the take Petrov, or red if they run with Maldonado. I've heard that the car may be light blue even if the take Maldonado because Campos himself is said to be looking at a silver strip. Silver and red would be too much like McLaren. And given the way they ran their GP2 cars, there will probably be red and yellow - the Spanish flag, of course - on the nose or on the air intake.
Lotus' colours are harder to call. The Lotus maque's colours are yellow and green, while Malaysian auto-racing colours are yellow and white. I can see some combination thereof being run on their car.
As for USF1, red, white and blue is the obvious choice, but I think it would be sacreligious to plaster sponsor decals oer the stars and stripes. I think they could run a stars-and-stripes motif on parts of the car where there are no sponsor logos, though.
