2009 wasn't really a good race from Hamilton: he spun twice and finished behind Kovalainen.Have to agree. Hamilton has always been strong at Shanghai. Should have won in '07, did in '08, '09 he didn't have the car but still came in a respectable 6th, in '10 he was bearing down on Button and in 2011 he became the first repeat winner of the race.
I reckon we'll see Mercedes and Lotus come to the fore as well. Raikkonen said the car had the pace to challenge for pole in Malaysia, if Rosberg stops 'cocking-up' I seem him joining the the battle for pole as well, however I'd expect him to drop back in the race.
I'm also going to say Massa has until Spain to get his act together and get somewhere near Alonso, because Ferrari can say they're standing by him all they want, I don't buy it.
The track is a lot like Sepang, so I'd expect the same cars to be fast in China as well: McLaren, Mercedes and maybe Lotus.
