Button once again showed that he can have a car come to him, and it seem that he should be well placed with the new rules next season.
I think that 2009 have given us a good championship, Vettel in my view is 'the real deal', and must be one of the favorites for the championship next season, Webber have finally delivered on his potential, and even though I seem him less of a complete driver than Vettel, he have established himself in the better half of the grid.
Kobayashi needs my grunding respect, we have seen other drivers struggle coming in to F1 this season (or switching team), and being as strong as he has been the past two races obviously is showing that he has something.
Heidfeld did his usual type of race, not really anything to note, but brought the car forward and finished in the points again.
Nakajima is the reason that BMW ended in front of Williams, who as a team have learned what we all know. You need to drivers strong enough to deliver over a full season, the difference between Rosberg and Nakajima is simply not good enough.
Next season is far away, and winter testing will show some teams to once again having missed something in the design department, at this time of writing I will expect Ferrari, McLaren, Red Bull and Brawn as Grand Prix winning teams in 2010.
Last race over, Button is now officially the World Drivers Champion, congratulations to him, he have come of age as well this season, and Brawn have shown how good he is to have involved in your team, the Mercedes link will only become stronger, so part of the budget shortfall Brawn had over the season, will be taken up and funded by Mercedes.
The next couple of weeks more seats will be confirmed, and the last likely not until the other side of New Years.
