Well recent reports were Williams were going bankrupt and could have been looking at leaving F1.
Now however it would appear from testing, and general word around the paddock, that they may just have one of the quickest cars this season.

Obviously until all the teams get together on a clear track it will be difficult to tell for certain, but from what I can gather from internet reports and hearsay, the car is by far the most consistent of the pack at this stage.
On the other side. Renault have cancelled next weeks test so they can get back to the factory and basically overhaul the car.
Mclaren are also struggling at this stage and have been forced to go back to the 2008 rear wing to provide some rear stability while testing the various other systems. They're also having to use Flo-vis paint to find out just whats going on with the CFD calculations.
Mic keep an eye on the Kemble website if there is one as Renault will likely be back there.
Hoping to get some proper confirmation on these but like last year we'll prob have to wait till australia to see it.

The BBC will be releasing the information of how their coverage will be provided on the 22nd of feb.
