As well as all the street and road course options there are also a number of possible oval courses in the picture, with the one-mile, low-banked tri-oval Phoenix International Raceway (which last saw Indy cars race in 2005), the 0.75-mile asphalt D-oval at Richmond International Raceway (used by the Indy Racing League from 2001 until 2007) and the unique 2.5-mile tri-oval at Pocono (which last hosted a CART race in 1989) all being mentioned as possible hosts for races in 2013 or beyond.
"I've been doing a lot of traveling and talking to try and see who is serious about racing with us," Bernard said.
The new 3.4-mile F1 circuit at the Circuit of the Americas in Austin has also been much-mentioned as wanting to add IndyCar to the roster of events at the new facility, but with the now-confirmed Grand Prix of Houston together with the existing event at the Texas Motor Speedway, there is a possibility that even the huge Lone Star State might be stretched too thin to provide crowds sufficient to support all three events.
There's speculation that it's Texas that might end up dropping off the calendar after 2012, especially after an ongoing row erupted between TMS president Eddie Gossage and IndyCar drivers about the safety of the speedway resulting in angry exchanges over a mooted driver boycott of the race on safety grounds.
Texas is a high-banked 1.5-mile oval track, making it worryingly similar in many people's minds to the Las Vegas Motor Speedway where a 15-car accident last October claimed the life of Dan Wheldon. Although the official inquiry into the accident concluded that the cause was due to the interaction between the old-model IndyCar and the unique nature of LVMS, a number of drivers and experts fear that a similar conjunction of factors and other safety issues could occur at Texas with the new DW12 chassis.
Gossage is also said to be less than happy at having lost the prestigious next race slot following the Indianapolis 500, which usually benefits from a boost after all the media coverage of the Indy 500. In 2012, the 'next after Indy' slot has been filled by the return to the IndyCar calendar of the Detroit Grand Prix at Belle Isle.
