I sincerely hope that they take the opportunity to build a GREAT series that is NOT spec racing.
Remember, with no USGP in F1, there are ALOT of manufacturers (BMW, Honda, Toyota, etc...) that really want the US exposure. If the rules and regulations were set with the intention of becoming what F1 is "supposed" to be (top drivers, engineers, technology, etc), the new series could attract big manufacturers as well as drivers.
It would be great! And I would have to say that if the new Indy Champ League had those things, that I would cease to be a F1 fan, and immediately become a ICL junkie.
Here's hoping!
