Button has said he'll race for Wiliams in '06...Williams have agreed.
Look at it from Williams' perspective now though. They had Ralf Schumacher AND Monty...Now, they've got Webber (although I rate him) and potentially Pizzonia!?
They could still try and 'buy out' the contract of Buttons, but that doesn't look likely. Sadly, I don't think Davidson stands much chance at Williams now either (he before Button showed interest in the Williams seat was the prime target to race alongside Webber) so my bro's only hope is that the Midland UK team manage to purchase and run the ex-Jag team!
If neither of those options open up for him - he'll hopefully race at BAR in '06!!!!
I think Button may well be content with doing another year of BAR, I predict BAR will just give him an insentive to stay, i.e. more cash!
BAR are a good team. British American Tobacco are very rich. Button is a clean, smooth racer and this suits the car (this is why Taku is struggling)...
Also, BAR shouldn't opt for Bridgestone, as they put too much time into the Ferrari squad. At least with Michelin, they work on getting a tyre to work best for each car...where-as Bridgestone obviously just tailor make their entire package for Ferrari.
Anyway - I wish good luck to Button and also good luck to the Midland UK team to get things sorted for '05...
