Personally i can see Heidfeld going to be with Bob at Renault, as im sure that Sauber isnt gonna hang arround for long. Schumacher should be announced as soon as posible.
Id make a rule that teams should have all their driver lineups confirmed before the last friday before christmas. Same with engine deals and such as well.
Thats would really spice things up a little for the teams, media & fans alike.
