The American broadcaster Speed TV also revealed that Just Marketing, a local company, has been hired by the IMS to help find a formula one title sponsor.
Just Marketing president Zak Brown said George and Ecclestone have a "strong interest" in reuniting as soon as possible.
"If the right sponsors can be put into place, I think this can happen in 2009," he added, insisting that the interest from lucrative potential race sponsors is already "fairly high".
