Jaime Alguersuari says his plans for the 2013 season will be announced "very soon".
Recently, the former Toro Rosso racer and current Pirelli tester told his supporters that he was confident he would return to the grid next season.
He told them the plans would be revealed "soon".
A reader of Spain’s sports daily AS asked Alguersuari, 22, if ’soon’ had now come and gone.
The reader told the music-loving driver that if he was in charge at McLaren, he would have signed him to replace Lewis Hamilton.
"But apparently without billionaire sponsors, it’s impossible," the reader said.
Alguersuari responded: "Ha ha, thanks!
"I will reveal my plans for 2013 to all my fans very soon. Thank you for your support."
Force India is tipped to announce the identity of Paul di Resta’s new teammate for 2013 this weekend in Brazil.
