Both venues are in the same broad time zone as the continental US, making TV scheduling straightforward for both events. But the series has struggled to move further afield, with the proposed 2012 race in China falling apart at the last minute and the traditional Japanese round at Motegi coming to an end after the 2011 event.
The appeal of Motegi was because it was the home of then-exclusive series engine supplier Honda, and it's likely that Mugello has entered consideration because it is owned by Ferrari. The series is looking around for more engine suppliers to join the competition in the future, and Fiat subsidiary Ferrari would be high on the list of prime candidates.
Reports say that Bernard has also discussed the possibility of Ford entering the series as a manufacturer, but that they are unlikely to sign up in the near future. Bernard is also said to have had discussions with Dodge, after the company decided to pull out of NASCAR competition at the end of 2012.
Currently Honda and Chevrolet dominate the manufacturer battle, with Lotus' entry into the series ending in ignominy as their engines under-performed and teams scrambled to break their contracts in their rush to sign up with one of the other suppliers.
