Williams' decision about whether to retain Nico Hulkenberg for next season is not imminent.
Williams considers 2011 drivers
While Rubens Barrichello is believed to have agreed terms for a second season with the British team, German rookie Hulkenberg's future is less secure.
It is rumoured Williams is looking into replacing him for 2011 with Pastor Maldonado, Hulkenberg's new successor as GP2 champion and substantially backed within Venezuela.
Barrichello admitted last month that the team was "analysing the Nico Hulkenberg situation" before scheduling an announcement about 2011.
Asked if Hulkenberg is still in favour at the Grove based team, chief executive Adam Parr answered: "Absolutely."
But asked for details about the delayed confirmation of the team's next lineup, he answered: "I cannot go into that," adding that he doesn't know when an announcement will be made.
Asked if the 'cards are in the air' regarding Williams' driver lineup at present, he admitted: "I am afraid they are at the moment."
