Kimi's too far back to get all the way up to 1st, unless he saves most of his KERS for the long stretch into and out of Eau Rouge.
I think it will be Barrichello, Raikkonen, Glock or Webber 1,2,3 respectively. Trulli will pull his usual fade after the first stop and the Force India and Saubers won't stay in the top 5 for the whole race.
I don't see Button making it into the points, may get lucky though and pull off a single point.
