A decision about whether to add a 20th race to the 2013 schedule will be made next week, with Istanbul the favourite to take the place of the postponed race in New Jersey, if a replacement is chosen at all.
The FIA World Motor Sport Council published a revised fixture list during December 2012 that accommodates a 20th race on July 21, a slot between a rescheduled German Grand Prix and Hungarian Grand Prix.
The FIA also confirmed that this race was reserved for a European host, with in Turkey, France and Austria mooted as possible venues.
Formula One supremo Bernie Ecclestone played down the chances of returning to the Red Bull track in Austria's Spielberg mountains, and with François Hollande's recently elected national government's decision to cut public funding in France, Magny-Cours seems an unlikely venue as well.
"At the moment, I'm thinking more about Turkey and a return to Istanbul," Ecclestone earlier.
The proposed Turkish Grand Prix is not without its problems, however.
During December Turkish minister of sport followed the direction of his French counterpart and confirmed that no public funding would be made available to help revive the race that normally took place just outside the country's biggest city.
"Just now, I am thinking we might have only 19 Grands Prix this year," Ecclestone added.
"That would not be a big problem for Formula One. Probably we will be able to reach a decision next week."
