Well with regard to the Red Bulls they have really pushed the envelope in terms of overall design and getting the whole package working. I wonder how much they have had to compromise next year to keep this years car so good.

The interesting move is Massa to Williams, Williams have a chance to make a step forward next year, they have all kinds of resources that the other teams they are racing against don't have and so could seem them pushed towards the front.
The issues with pay a lotus is again worrying how that would affect the new development.
Raikkonen to Ferrari I think gives them the best team overall, but without a natural 1/2 there might be some friction.
