Heikki Kovalainen, Bruno Senna and Nico Hulkenberg have all dodged questions about their F1 future.
Kovalainen is out of contract with Caterham at the end of the season and admits that remaining with the team is a likely option.
"Nothing's been signed for next for myself yet. Personally, my target and my focus is at each race weekend for our team it's quite important that we try to regain that 10th position back from Marussia", he said. "Regarding the future with the team and with Tony, we haven't decided yet. I think Tony knows what he gets with me but then he's evaluating other options I think to see what he wants to do. And I'm waiting. In the meantime, of course, my management is also working".
Bruno Senna is under pressure at Williams from Valtteri Bottas. The Brazilian insists nothing has changed since the Korean Grand Prix.
"Nothing has changed from the last time I was here and you asked me the same question but the focus is still the same: keep pushing and trying to get points for the team and then hopefully be on the grid next year", he said.
Nico Hulkenberg has been heavily linked with a move to Sauber for 2013, although the German was remaining stony faced during the press conference.
"I know there is lots of talk about my future but at this point I don't want to make a comment on the speculation. I'll just focus on this weekend, which is the most important thing", said the Force India driver.
When pushed about his plans, Hulkenberg added, "Just no comment".
