@cstonehouse – I’ve heard that Bernard wants the series to expand out to 20 races in 2013 (and possibly as many as 24), and that he’s been in talks with the following circuits:
Ovals
Michigan, Phoenix, Pocono, Kentucky, Richmond, Gateway, Kansas, Nashville, Homestead and Chicagoland.
Road courses
Portland, NOLA (New Orleans), Virginia, Road America, Sepang, Sentul, Losail, Mexico City, the Circuit of the Americas and “former Formula One venues in Europe”.
Street circuits
Cleveland Airport, Surfers Paradise, Chicago, Fort Lauderdale, Providence, Marina Bay (Singapore) and Palm Springs
Undefined (but probably street circuits)
Vancouver, Calgary and Quebec City.
The overwhelming majority of circuits being considered are ovals. I don’t think an international expansion would work, unless it was to Canada, Mexico or Australia and New Zealand. I haven’t heard anything about the potential for expansion to Australia aside from the Surfers’ Paradise race, and there is no way V8 Supercars will relinquish their hold on the event.
The best way forward would be an eighteen or twenty-one round calendar, with the ovals, road courses and street circuits split equally (so six, six and six, or seven, seven and seven).
