The picture that's emerging now is of a driver lineup that is nowhere near as set in stone as it once was, even for drivers who supposedly have contracts.
I never thought Webber would be at Red Bull in 2011 since the end of 2009. That's no shock to me and I predicted that Raikkonen would be a shoe-in at that team. It's still a possibility but I'm not sure now. Red Bull clearly have mental issues over drivers getting the upper hand over Vettel and drivers like Raikkonen, Kubica or even Heidfeld would all be out.
What will be really interesting is if Massa has had enough, as the rumours still swirl, and finds himself a seat he's happy with. Kubica might also then be available.
