If they keep making X-Men movies, they keep X-Men characters covered by Marvel's "X-Men" franchise as per their deal in 1994 and further X-Men characters sent to Fox up to the Disney takeover, coming to a total of just over 800 X-Men characters

For rather bizarre reasons Deadpool was not included in those 800 and Fox had to acquire him separately (Marvel saw "potential" in him and sold him to someone else, so Fox had to get him off them). To all intents and purposes he is a third franchise, even if they do use him with the X-Men characters he has his own timer ticking away and everyone is keeping an eye on it (because thanks to breaking off bits of the "franchise" in the 90s, they have already reacquired Alpha Flight and the Savage Land).
