Would love to see Kimi back at Macca and Kubica at Brawn. The former looks likelyish, but sadly Rosberg looks set to take the second seat at Brawn to keep Merc happy.
The current talk is of Villeneurve racing for one of the new teams. Would be interesting if he could get anywhere near the pace of the current grid, but he has looked continuously average since 1997. Having said that, another WC on the grid has to be good for the profile of the sport.
