It is possible that the U.S. will be just two Grand Prix Formula 1 in the year.
According to reports in the American press, as early as next week will be officially published plans to organize a street race in New Jersey. The first phase is scheduled for 2013.
The United States has already prepared to the Grand Prix in Austin (Texas), but the Formula 1 boss Bernie Ecclestone has repeatedly stated that he wanted to spend in America one more race. Apparently, these plans are close to Bernie implementation.
Presumably the Grand Prix of New Jersey will be held in June, so this race may be coupled with the Canadian Grand Prix. Austin, in turn, will be held in conjunction with the Grand Prix of Brazil.
