Well, as a Brit I'm hoping Hamilton does it, but I do have mixed feelings about the season.
If it wasn't for engine failures and pit problems (i.e. stuff out of his control) then Massa would probably have enough points for the title already.
However, he didn't really deserve the victory handed to him at Spa (either Hamilton or Raikkonen would've been a worthy winner). Plus the extra point he gained in Japan (with Bourdais being penalised) still mystifies me.
Hamilton has seemed intent on self destruction a couple of times this year, and just can't keep his head when it matters. Yet, I do believe he's the better racer of the two (Massa never strikes me as the kind of guy capable of scything through traffic like a Schumacher, Alonso, or even a Hamilton).
Kubica has impressed me the most this season, though hats off for Alonso for making the most of his car recently.
As for winning the title, it seems to me that McLaren should just fuel their guys really light for qualifying; in the hope of locking out the front row. Cross fingers they get away safely, then compromise even further by trying to ensure Hamilton comes out of pit stops in clear air (even if that means bringing him in really early). You're going to lose places doing that, but trailing home in fifth, having protected the car, is better than going out in a ball of flames and losing the title.
I just hope that other drivers (that's you Fernando) let the guys fight it out without interference.
Prediction for the weekend: Hamilton does a crazy start, causing a massive pile up. Stewards give him a penalty and he ends up at the back of the pack. A bored Raikkonen tries to perform the "Ferrari Swap", allowing a struggling Massa through, but they collide and take one another out. With the title secured, Hamilton races through the pack, before going off the road due to oil from a Kovalainen engine blow up. Only two cars and a dog finish the race, with Button's dog of a Honda's getting the win (though being heavily challenged by the dog on the final straight). FIA stewards later decide that Button's Honda was actually Massa's Ferrari (it was a trick of the light), and order Hamilton to be shot in front of a baying crowd. An FIA steward later explains, "We thought it'd be a laugh". I'd buy that for a dollar.
