Reports have suggested that Gomis is attracting interest from England, with Chelsea in pole position and said to be already in talks with Lyon.
Liverpool have also been linked with a move for the striker as Brendan Rodgers seeks some attacking support for Luis Suarez.
Gomis believes there will be developments early in 2013, indicating that he could be moved on if he does not pen a new deal.
Commenting on stories that Lyon president Jean-Michel Aulas may sell him this winter, Gomis said: "I have heard it, the president said I will get transferred or will renew my contract before the end of the January transfer window."
Lyon were knocked off top spot in Ligue 1 by Paris St Germain on Sunday night following a 1-0 defeat at Parc des Princes, but Gomis insists there were plenty of positives to take.
He said: "For the game tonight we showed we were top on merit, we played well against a top team and produced a good game."
