Those weights would indicate that the pole lap was very special. Providing nothing out of the ordinary happens, Hamilton really should win tomorrow's race.
It looks like McLaren are finishing strong, which bodes well for 2010, assuming that the 2010 car will be an evolution of their 2009 car.
What will be interesting is to see if McLaren decide to equip KERS to their 2010 car, given that they have made a gentleman's agreement, even though Hamilton is able to use KERS which gives him a significant advantage. Mclaren certainly will need to take any advantage they can use, given that it looks like they will be up against Ferrari/Alonso next year, which is not going to be easy.
Providing Alonso does move to Ferrari, next year should be a cracking one where Hamilton and Alonso can finally resume their rivalry (something that has been missing since 2007).
Another point to note is the atmosphere created by a night race is beautiful. Day races just don't project the same atmosphere, as the night race. Of course it helps that the area around the track is stunning.
Button seems to be making a meal of the 2nd half of the season. I guess the pressure is getting to him. Providing that he finishes the remaining races, he should still win the title. His problem will be if he has a non-finish, with Barrichello scoring a hatful of points. The pressure of fighting for the title in the final race of the season under those circumstances could see him implode, in a car which is clearly suiting Barrichello.
