"We will have 20 races [in 2014], Austria included," Ecclestone told Austria's Kleine Zeitung
newspaper. "Everything else I don't know, please ask me again after the summer."
That's put the question of which of the current 21 mooted races will lose out back on the gossip agenda thanks to its late postponement this year due to the local organisers falling behind in construction of the Port Imperial Street Circuit in Weehawken, and also having difficulty securing the necessary official permits.
The race, formally titled the Grand Prix of America, would be the second of the year in the United States along with the existing United States Grand Prix
at the Circuit of the Americas
in Austin, Texas.
However the New Jersey event is not the only race with a question mark hanging over it. The Spanish Grand Prix
had been due to the held at Valencia in 2014 as part of an alternating arrangement with the Circuit de Catalunya, but the street circuit is reported to already be in a dilapidated condition and no longer fit for F1 racing.
Elsewhere, South Korea is thought to be struggling to justify the race fee payable to Bernie Ecclestone's F1 commercial rights holder and considering pulling out of staging future grand prix events at the Yeongam international circuit. And there are ongoing concerns over whether the under-construction Sochi International Street Circuit will be ready to hold the inaugural Russian GP in October because of a clash with preparations for the 2014 Winter Olympic Games.
Ecclestone may well have more solid information about one or more of these cases and be planning accordingly, or simply be giving himself the 'spare' venue that he was lacking earlier this year when forced to delay the first New Jersey grand prix.
