Anyone who predicted that Honda would sell its team to its management for a reputed £1, go on to win both titles, and then become Mercedes GP, will have no trouble at all predicting what will happen next season.
The biggest thing to me that will upset any predictions is the lack of refuelling and the narrower front tyres, together with the lack of testing. The other is the performance of the Cosworth engine, which they can keep on developing right up until March!
And another, of course, is that 'General Circumstance' is likely to play a large part in just about everything!
