Sevilla are among those known to be keen on Gameiro, and the France international is ruling nothing out.
He has also been linked with a switch to England, with Liverpool reported to be leading the chase, while Borussia Dortmund, Valencia and Fenerbahce are understood to have enquired as to his availability.
With the 2014 World Cup now very much in his thoughts, Gamerio concedes that there is every chance he will be bidding farewell to the reigning Ligue 1 champions this summer.
He said in L'Equipe: "There is talk about Sevilla. I have to decide whether it would be better for my career to go somewhere else and not be satisfied with my substitute position in Paris.
"I want to play football and score goals. In one year there will be a World Cup, and that is a target for me.
"I have opportunities almost everywhere, but I do have a preference for La Liga."
While Gameiro suggests a transfer could be imminent, new PSG boss Laurent Blanc insists there is no guarantee that he will sanction a sale.
He said: "There are contacts. We have spoken and he has his own position.
"But Kevin is almost the only real centre-forward we currently have in the group. We will see what the club decides."
