Following the recent flurry of announcements, here is ITV.com/F1's guide to how the 2010 Formula 1 field is coming together.
McLaren-Mercedes
Confirmed: Jenson Button and Lewis Hamilton
Martin Whitmarsh's team has pulled off the coup of the winter by pairing the last world champions. Luring Button away from Brawn to join lifelong McLaren man Hamilton gives the Woking squad a mighty - and very sponsor-friendly - line-up.
Mercedes
Confirmed: Nico Rosberg
Nico Rosberg has finally been announced by Mercedes, and with Button opting for McLaren, it seems an all-German line-up could be on the cards, with Nick Heidfeld - a Merc protege in his youth - mentioned in connection with the second seat. Kimi Raikkonen's management have hinted they would be willing to listen to a Mercedes approach, but the team is surely unlikely to offer Raikkonen the "perfect deal" he desires - unless Mercedes decides a Rosberg/Heidfeld line-up is just too lacking in star power. Michael Schumacher has also featured in feverish recent speculation.
Red Bull
Confirmed: Sebastian Vettel and Mark Webber
Red Bull took itself out of the silly season early on by swiftly announcing it would retain rising superstar Vettel and gritty, proven winner Webber - a just reward for their 2009 success.
Ferrari
Confirmed: Fernando Alonso and Felipe Massa
After years and years of rumours, Alonso has made his Ferrari move. The team is confident the recovering Massa will easily be fit enough to take up his place in the second car.
Williams-Cosworth
Confirmed: Rubens Barrichello and Nico Hulkenberg
Williams has gone for a blend of youth and experience - hiring Barrichello after his 2009 renaissance at Brawn, and promoting highly-rated test driver Hulkenberg following his impressive GP2 title triumph.
Renault
Confirmed: Robert Kubica
Despite some lingering doubt over the company's F1 commitment, Renault has signed up Kubica to fill the void left by Alonso. The silence over his team-mate's identity could be related to those future rumours. Timo Glock was briefly favourite but opted for Manor, and Heikki Kovalainen has also been mentioned, but Romain Grosjean will be fortunate to get another chance after his poor half season.
Force India-Mercedes
Confirmed: Adrian Sutil and Tonio Liuzzi
The talented but erratic Adrian Sutil gets a fourth season with the team, while Tonio Liuzzi showed enough speed in his five race outings to earn his first full-time F1 seat since 2007. Paul di Resta and JR Hildebrand are testing for Force India at Jerez and are both in contention for the reserve seat.
Toro Rosso-Ferrari
Confirmed: Sebastien Buemi
Toro Rosso put out a statement on its website several months ago effectively saying 'Buemi and Jamie Alguersuari are staying on, so leave us out of the rumours please'. Since then, there has been a little vagueness over Alguersuari's status, although none of the other Red Bull drivers - his most likely rivals for the seat - look ready for F1 at present.
US F1
No drivers confirmed
An endless array of American racing superstars have been mentioned as 'possible eventual candidates' for US F1, but the team bosses do not expect to have an American driver in the project's first year. Former Renault test driver Jose Maria Lopez is a leading candidate if he can find the rest of the money required.
Campos Meta
Confirmed: Bruno Senna
Senna gets his deserved F1 break with the new Spanish squad. Campos was originally expected to sign experienced McLaren tester Pedro de la Rosa, but looks like it might require a driver with funding as the loss of the budget cap came as a blow. Reports in Brazil suggest Nelson Piquet has approached Campos recently.
Virgin
Confirmed: Timo Glock
Ex-Toyota man Glock will lead the Manor team, which has been entered under the Virgin Racing title, and will probably have a young driver as his team-mate. Lucas di Grassi has been tipped for the seat.
Lotus
No drivers confirmed
Jarno Trulli's close ties with Lotus technical boss Mike Gascoyne could see him lead the team. Gascoyne is keen to have two experienced drivers, but team chief Tony Fernandes has hinted at a 'youth and experience' pairing. Both have dismissed early rumours of a race seat for top Malaysian driver Fairuz Fauzy.
Sauber
No drivers confirmed
The former BMW team remains in a state of flux until the FIA officially awards it the entry left vacant by Toyota's withdrawal, but the sale back to Peter Sauber should put it on a stronger footing. It looked like this team might be Heidfeld's best bet until the Raikkonen/Button situation opened up bigger opportunities for him. Ex-BMW tester Christian Klien could be an option, though.
Waiting in the wings
Unsigned 2009 drivers: Jarno Trulli, Heikki Kovalainen, Giancarlo Fisichella, Kazuki Nakajima, Nelson Piquet, Romain Grosjean, Kamui Kobayashi
Fisichella says he is open to any race team offers that he could combine with his new life as Ferrari's reserve. Piquet has financial backing and wants an F1 return despite his role in the Renault race-fixing scandal. Kobayashi looked a dead cert for a 2010 Toyota drive before the team's pull-out, but Toyota has hinted it could help him find a slot elsewhere. Fellow Toyota protege Nakajima's chances look more remote given his poor 2009 form for Williams.
Blasts from the past: Jacques Villeneuve, Pedro de la Rosa, Christian Klien, Alex Wurz, Anthony Davidson, Takuma Sato, Franck Montagny, Michael Schumacher
Former world champion Villeneuve is openly chasing an F1 return three years after his mid-season split with BMW. The sidelined Sato has been approaching teams, while many would love to see his former Super Aguri team-mate Davidson back on the grid, but the Briton's perennial lack of sponsorship makes a return a long shot. Montagny, another ex-Super Aguri man, has also been the subject of surprise F1 comeback gossip.
From GP2 and beyond: Lucas di Grassi, Vitaly Petrov, Pastor Maldonado, Andy Soucek, Karun Chandhok, Bertrand Baguette, Paul di Resta, Jose Maria Lopez
GP2 frontrunners Petrov, di Grassi and Maldonado hope the new teams might open F1 opportunities for them, while Formula 2 champion Soucek is keen to capitalise on his forthcoming prize Williams test.
