I don’t think he is in the same stature as Jorg Zander.  Rumour has it that Geoff has been pushed.  The reasons behind are unknown although again it is alleged that Adrian Newey and Geoff Willis haven’t always agreed on technical issues at Red Bull Racing.  Sebastian Vettel certainly miss his contribution as he says it won’t have any destabilising effects.  Another Mike Gascoyne I guess.  Apparently, like Mike he has offered his services to Ferrari but as to where his next movements are nobody knows.  Manor Motorsport perhaps?
