Webber to leave Jaguar? Sounds like it
Williams, which is looking for two new drivers, or big-spending Toyota are the most likely destinations.
"I know everything, you guys know nothing," Webber said with a smile at a British Grand Prix news conference on Thursday.
"And that's how it will be today.
"It's quite interesting at the moment. Some decisions have been made I suppose, so we've just got to see how it all pans out in the next two races."
Williams must find a new lineup after Toyota confirmed on Wednesday it had signed Ralf Schumacher on a three-year deal.
Colombian Juan Pablo Montoya agreed last year to join McLaren in 2005.
Williams technical director Sam Michael, also an Australian, said in Canada last month that Webber was the team's top target to replace Montoya, but paddock speculation has recently put Toyota in the frame as well.
Webber is contracted to Jaguar for one more season but there are believed to be performance clauses allowing him to leave if Jaguar has not reached a top six position in the championship by next month's Hungarian Grand Prix.
The Ford-owned team is currently ninth.
Jaguar, a Formula One debutant in 2000, has yet to take a point from a British Grand Prix and Webber last scored at the Nurburgring in May. He was ninth in France on Sunday.
"To match Magny-Cours could be difficult to be honest, we'll just have to see how it goes," he said. "Weather is obviously going to play a huge part.
"Our aero package is definitely one of the stronger parts of our car so I'm hoping we can go well.
"We're not the quickest car around here but we're not the slowest so we'll see where we end up."
The Australian arrived at Silverstone after paying a flying visit to American Lance Armstrong at the Tour de France on Wednesday.
"I admire people that can do things that I can't do," said Webber of the five-time Tour winner. "I don't have many racing drivers as heroes...I look up to people like Lance because of what he's gone through.
"I enjoyed that, it was bloody awesome, he took the yellow jersey yesterday...then I came back in the helicopter and got stuck at Dover because of the weather so I had five-and-a-half hours on a train yesterday."
