Question is will BrawnGP and RedBullF1 remain strong contenders?  I think Brawn will have the most to overcome...as they will not have the advantage of a trick diffuser as they did in 2009.  My guess is RedBull will compete and Brawn will stuggle to stay in the top 5.

If  Hulkenberg is confirmed for 2010 he should do well.   He has Willi Weber as manager and could replace Rosberg at WilliamsF1.. 

Nakajima won't stay in Formula 1, he's pretty much already got a drive in Nascar next year. Who will be the second driver at Williams?  It could be Jarno.

It's always hard to judge how well a new team will do in their debut season - especially with four new teams coming in. I would hazard a guess that Lotus will be the most successful, with Manor being the least, but I won't have viable reasoning for that until I've seen the drivers line-ups and the cars for the season.

With 26 cars on the grid and just 8 points scoring places, there WILL be a team, perhaps two or three, that end the season on 0 points. I wonder how many of the 2010 teams will be back for 2011? Another factor to the 0 points mark, is that there seems to be a lower attrition rate in recent seasons than in the 90s or early 00s, say. So they'll be teams racing around for two hours and finishing 13 places off the points. It will be a challenging season for all the new teams, and an opportunity for Toro Rosso/Force India to prove they're not a straddling team.

Will be really interesting to see if the Cosworth Engine really does have 30BHP on the rest of the field and whether they can stop it grenading! If so I think my money will be on Lotus! its going to be an interesting start to the season! 

I think it's unlikely any of the new teams will be a major success next year, simply because they won't have the expertise in place, but Force India might produce a surprise. 

Toyota I think might vanish altogether. What success they've enjoyed has been by throwing money at it, which is an option they no longer have. Their drivers are skilled but not good enough to compete in average cars against the front-runners, so the parent company will probably finally pull the plug.
