Lewis Hamilton insists his plans for 2013 are undecided

McLaren's Lewis Hamilton says he does not know which team he will be driving for next season.
BBC F1 chief analyst Eddie Jordan reported on Wednesday that Hamilton, whose McLaren contract runs out this year, had agreed terms with Mercedes.
But when asked if he knew which team he would be with for 2013, Hamilton, the 2008 world champion, said: "No."

The 27-year-old Briton added: "I want to win. Just need to think of the right place to do so."
But he echoed his management's statement on Wednesday that he was "in advanced negotiations with McLaren", adding: "That's what we're working on."
Hamilton, who drives alongside fellow Briton Jenson Button at McLaren, said he did not have a deadline for a decision and insisted he was focused on the remaining eight races of the current campaign.
"I'm in a great position and I just need to focus on the preparations for these races," he said.
"There is a long way to go. Jenson has shown we have great potential in our car and team. That's what I need to focus on."
Hamilton has had a mixed season so far. He won in Canada and Hungary but lies fifth in the standings, 47 points adrift of leader Fernando Alonso in his Ferrari.

But Button believes his countryman will remain with McLaren.
"I think I'll have the same team-mate next year because this is the best place for him," said Button, speaking at an official news conference ahead of this weekend's Italian Grand Prix at Monza.
