I think Bernie will have to do some serious bargaining to get the other teams on board. At the moment, the rival series is looking pretty strong. With manufacturers like Daimler, BMW, Honda, Toyota and Renault on board, there is potential for an even better series where technological advancement is not quashed by the powerbrokers.
As for Ferrari, I hate the way they operate and always seem to get away with their misdemeanours. They are losing their appeal to the fans now especially due to this petty refusal to allow Minardi to use the old car. To be honest I have only disliked ferrari since Schumacher & co. went there. Since then they've always given me an "up to no good" feel about them.
Anyway, it looks like it'll be a McLaren v Renault show this year. Hopefully the Iceman comes out on top!
