The Spaniard, speaking after Bayern's 1-0 German Cup win over Darmstadt on Tuesday night, told reporters that all will become clear next week.
And reports in England and Spain are now claiming that City remain in pole position to get the coach their two former Barcelona executives Ferran Soriano and Txiki Begiristain were brought in to deliver.
"Tonight, I have no answer," said the ex-Barcelona boss, whose contract expires in the summer. "Next week there will be clarity."
Bayern chief executive Karl-Heinz Rummenigge revealed last month that he will hold talks with Guardiola after the German champions play Hannover this Saturday - a date that seems to have been a final ultimatum from the club as they seek an answer over his intentions.
He said: "It is not planned to push back that date. We have always said there will be a decision in 2015.
"I know that it's late, just days before Christmas. But the talks will be held after the Hannover match, and we'll then announce a decision."
But Guardiola appears to have now made up his mind to leave the German club, who are being tipped to bring Carlo Ancelotti in as his replacement next season.
