With Fuji pulling out of the Grand Prix swap arrangement the door has been left open for Suzuka to be the permanent host of the Japanese Grand Prix, My personal opinion this is a good thing, I prefer Suzuka over Fuji.

Both Championships could be decided this weekend, for Button he needs to better Barrichello by 5 points and the title is his, the 20 point lead means he can't be overtaken and his 6 wins can't be caught by any of his rivals

Brawn currently lead the constructors title by 42.5 points and will be crowned champions as long as they at least equal Red Bulls points haul, in fact as long as Button and Barrichello pick up 12 points between them in the last 3 races they will win the title regardless of what Red Bull do even if Vettel and Webber finish 1 and 2 in all 3 races which is not likely.

Other Notable battles

Ferrari lead Mclaren by 3 points, this annual battle, normally reserved for the constructors title rather than 3rd and 4th but neither team will want to finish below the other, for Ferrari that means getting Fisichella up to speed and quickly but with no testing that probrably wont happen and with Mclarens recent speed.

Hamilton is 3 points behind Raikkonen too and with the reports Kimi is moving to Mclaren or has at least signed a pre-agreement subject to getting out of his contract at Ferrari both will want to not only beat the other will see Webber as a target.

It looks like Toro Rosso will be ending up with the wooden spoon, Force India's assurgance for a couple of races has given them an 8 point lead and barring a race or 2 of high attrition i can't see them getting them and thats if Force India don't pick up any more points.
