@KaiJin: Vergne, probably. Hasn't done a whole lot wrong.
@kkunakorn: Nope, that's not confirmed. It's all a bit strange at the moment, to be honest, suggesting there may well be a twist in the next few weeks. But most insiders say Vettel has signed for Ferrari.
@jdenn: Ricciardo is currently in the garage and won't be coming back out, he's got an ERS issue.
Rosberg has improved to 2nd, a tenth off Hamilton, who has just gone purple through the first sector.
Sutil has spun at Turn 19 and continued. DRS was momentarily disabled and that might well have been why.
Hamilton extends his advantage by 0.06s, not as much as it looked like he might after going purple through the first two sectors.
@kkunakorn: It depends how much you want to read into things. As far as I see it, Vettel is off to Ferrari, there's no question about that. The real question-mark continues to be about Alonso.
Magnussen shaves a few tenths off his current time but does not improve on fifth, he's nearly a second down on Hamilton and seven tenths off Button.
@Katsuramoneh: I'm sure that thought has entered his mind as well.
@KaiJin: If he ends up without a drive, it will have been his own doing. Trying to keep as many options open as possible and seeing them close up in front of him. But yes, for a man of his talent, it would be hugely unlucky.
@WtF1: That's another area people just aren't sure about. McLaren racing director Eric Boullier recently said it would take teams six months to get everything ready for a third car. The whole thing has so many grey areas it's a tad ridiculous.
@Prakhar: No. When Vettel announced he was leaving Red Bull, the team immediately confirmed it had signed Kvyat for 2015 to partner Ricciardo. Red Bull's line-up is locked in.
@Nikhil: I'm a journalist, not an Alonso fan. I just call it how I see it.
@GaneshBala: Well, Alonso recently said he wouldn't be driving a Mercedes-powered car next year.
Turn 19 proving to be a real handful for the guys out there, with Magnussen the latest driver to shake his tail feather coming through there.
@Jason: He did, but if a driver is in talks with a team for next year he is going to know who they are in talks with etc, so he probably knew Lotus was included in that.
@satyaban: He's got an ERS issue and won't be emerging from the garage for the rest of the session.
We're into the final 20 minutes of this session, with just Hamilton, Kvyat, Alonso and Vettel out on track.
@Katsuramoneh: I don't think Hamilton would do that, purely because he believes he is the fastest man out there and doesn't seem to mind who his team-mate is. Also, he still needs to negotiate a new deal beyond 2015 at the end of this year, so taking that approach wouldn't be the wisest approach.
@tony: I think it's hard to call with a lot of the drivers further down the order - a good example being Ricciardo, who has now been able to show his talent now he's been given the car. But Alonso clearly is world class talent F1 doesn't see often. Of the current grid, I think only Hamilton comes close in terms of being able to win races in uncompetitive machinery, as they have both done in previous seasons.
@WillAudibuyupa...: Audi despises the way Ecclestone does business, which has prevented them from entering the sport before. Audi and the VW Group have both denied its future involvement in F1, so I think a lot of people are clutching at straws a little bit.
Alonso has a big slide coming out of the final corner.
@Prakhar: Yep, that's one of the rumours doing the rounds. As a journalist I can safely tell you that no journalist in the world really knows exactly what is going on, so there is a lot of guess work. Until we hear from the man himself, we won't know - even if the waiting is unbearable!
