There really are a trillion rumours pinging around the place. Maybe I could help clarify a few things, driver by driver:
CURRENT DRIVERSLewis HamiltonHas McLaren contract for 2010.
Heikki KovalainenLikely to get the boot, and McLaren not confirming him at the same time as Hamilton strongly suggests he will leave. Goodness knows where he would end up, but has been strongly linked to Renault, and Toyota and Manor have also been mentioned at times.
Kimi RaikkonenFree Agent. Very strong McLaren rumours, but nothing confirmed from either side. Kimi's not even sure he wants to continue in F1 now. In reality, he will go to whatever team he likes, everybody except Ferrari and Red Bull have free seats avaliable for him. But could end up leaving F1 altogether and moving to Tommi Makinen Racing instead.
Felipe MassaHas Ferrari contract for 2010.
Nick HeidfeldCurrent team, with whom he had a contract for next year before the team sale, has no entry at present. Not that many options, and hasn't really been linked to any seats. If Qadbak gains entry, he will likely stay put, if not, he will have to hope one of the new teams pick him up post-season, otherwise it could be over and out from "Quick Nick".
Robert KubicaApparently a shoe-in at Renault now, but we will have to wait until next week to see if this is the case. Also linked to Williams. Brief mentions of Toyota too.
Fernando AlonsoFerrari contract for 2010
Romain GrosjeanRenault or bust it seems. Flav's exit from Renault dents his chances somewhat, new management may want to go with a different type of driver, possibly Kovy.
Jarno TrulliFree Agent. Is not renewing his Toyota contract, and unless he pulls a Fisichella and lands a Force India ride (which is unlikely if Sutil stays) his only other realistic options are the new teams. Otherwise, retirement could beckon for him.
Mark WebberConfirmed at Red Bull for 2010.
Sebastian VettelConfirmed at Red Bull for 2010.
Sebastien BuemiPress Release by STR implied he was to be retained next year, but hours later this was denied. Another driver who really needs his team to resign with him, his options elsewhere so far have seemed non-existent. But, of this years rookies, his prospects seem a little better than most.
Jamie AlguersuariSame goes for Jamie as his team-mate, and his only other probable chance is at Campos, if Adrian goes all soft and picks a pure-Spanish lineup.
Jenson ButtonNot 100% sure on this one. I think he signed a contract extension with Brawn a few months ago, there was some debate on that back then, but he appears to be staying put at Brawn for another year.
Rubens BarrichelloRumours of move to Williams, complementing Patrick Head's comments the team needs an experienced driver made a few months ago. New teams are also a possibility, but hopes of retaining his Brawn seat are fading as the days go by.
Adrian SutilLinked to McLaren as replacement for Kovalainen, and not exactly a bad bet now, depending on what Raikkonen does. Otherwise, staying put at Force India seems likely, and Williams has also been mentioned but looks extremely unlikely now.
Vitantonio LiuzziProbably has a contract with Force India for 2010. Not confirmed by either party, but Liuzzi said he had a contract with "one of the current [2009] teams", which is reasonably safe to assume is Force India considering his promotion to Race Driver after Fisichella's departure.
Nico RosbergWas initially linked with McLaren, but now looks likely to replace Rubens at Brawn GP. Frank Williams' optimism fainting as the days go by.
Kazuki NakajimaWill probably be kicked out by Williams. Toyota his best chance, otherwise, he could be left without a drive next year.
And now, the TEST DRIVERSPedro de la RosaFrequently linked with Campos. His last chance at F1. If he fails, he'll either be a tester forever or just retire on the spot.
Anthony DavidsonBrawn GP Reserve has been linked with Manor. His "recent" F1 experience could be a useful bargaining tool. Otherwise, his prospects are little to none.
Paul di RestaAnother McLaren tester, DTM frontrunner, has also been linked with Manor, as well as Force India. But, its the DTM, and graduates to F1 from there are few and far between. Hopefully he does get a decent ride though, he has the talent.
Alex WurzAnother Brawn GP tester, his chances are pretty much dead, unless a few of the new teams pull out and Superfund get the nod.
Lucas di GrassiHis only connections are to Renault, and is second choice to Grosjean. His prospects aren't good then. No other rumours, looks like he will be consigned to another year of GP2.
Gary PaffettAlmost zero. New teams are his only shred of hope. Otherwise, it will probably be DTM for life.
Christian KlienWill likely race for Qadbak if they recieve an entry. Otherwise, his chances are effectively zero.
Kamui KobayashiToyota his only option. Otherwise, its another year of GP2.
Nico HülkenbergThe most exciting young prospect of the year. Looks set for Williams, but manager Willi Weber says they are in talks with a number of teams.
THE RESTTakuma SatoSorry, no news here, unfortunately
STR probably his only glimmer of hope, after being considered for a drive their last year. With less Red Bull input at STR, his chances may be slightly better than last time.
Vitaly PetrovKeith Wiggins' dream. Reasonably quick, heaps of cash. Linked to Force India and Campos. May end up at neither. If he doesn't get a seat at first, expect him to replace someone mid-season, at whichever team is the most cash-strapped.
Javier VillaSome mentions to Campos. Unlikely though.
Roldan RodriguezSame story as Villa.
Karun ChandhokLinked to Force India, on nationality alone it seems. Mallya says he won't hire him until his GP2 results improve. So thats a no basically.
Narain KarthikeyanSame as Chandhok. Prospects may be marginally better, has F1 experience, plus Tata money.
Bruno SennaStronly linked with Lotus. Bernie will do all he can to make it happen. Limited options elsewhere, but both Brawn and STR have been suggested at times. I think Williams was mentioned but pretty much ignored.
Fairuz FauzyLinked with Lotus due to Malaysian backing. Otherwise, his F1 prospects are Zero.
Alex YoongOutsider for Lotus. F1 "experience". Same with Fauzy, F1 prospects zero apart from that.
Mirko BortolottiThink I heard an STR rumour a while ago. Not much else.
Andre LottererToyota. Probably people jumping to conclusions, he races for Lexus in Super GT. Was also mentioned by Ferrari after Hungary.
Giorgio PantanoIs actively seeking drive with Campos. Won the GP2 crown with them. Not much else since then. Currently in Superleague aka Reject Series.
