Vettel era coming to an end, says Ecclestone

Speaking to Bild newspaper, Ecclestone said this season's runaway championship leader could even be knocked off his perch as early as next year.
"His domination will end, maybe in 2014. We're going to have completely new cars, new engines, new rules," said Ecclestone.
"That will be the chance for Ferrari and Mercedes to catch up with Vettel. Next year it might not be the best driver but the best car that wins the title."
Ecclestone said he believed the recent jeers that have met Vettel's last two race wins in Italy and Singapore were not due to him as a person, but due to his dominance.
The German has won the last three Grand Prix and seven in total this season, more than half the races, and leads Fernando Alonso by 60 points in the standings, with the Spaniard another 36 points clear of third-placed Lewis Hamilton.
"He doesn't give Fernando Alonso and Lewis Hamilton a chance, he's as dominant as (Ayrton) Senna or (Michael) Schumacher in certain periods."
