Bernie Ecclestone has dismissed the latest reports about Las Vegas potentially joining a Formula 1 calendar of the near future.
Speculation that F1 might host more American races often does the rounds, but the latest word from Las Vegas was that an event on the world-famous 'strip' is more than just fantasy.
However, Germany's Auto Motor und Sport now quotes Ecclestone as insisting: "The Americans talk a lot, but nothing happens."
The F1 supremo has also given an alarming quote about the future of the Brazilian Grand Prix, saying of the long-running race at Interlagos: "It could be that the grand prix in Brazil this year is the last."
Auto Motor und Sport said that the problem in Brazil is purely financial, as the national broadcaster Globo reportedly struggles with strict austerity measures.
There is better news about the uncertain future of the German Grand Prix, despite Ecclestone saying not too long ago that the country could fall back off the calendar for 2017.
He has now declared: "I can imagine there being a race in 2017."
The 2016 calendar continues this weekend with the European Grand Prix.
