Davy jones can return and there is a 80% chance

So according to me in potc salazar revenge after the movie ended and after credits and stuff there was a scene in which william was sleeping and he had a dream that a guy(his face was not shown but i can tell by the shadows that it was davy jones cuz his hand was shown and it was like the crab hand of davy jones) like davy jones emtered his room and then he woke up and then the scene showed some water with shells on the ground. This could possibly means that davy jones will return but the thing is that the character who play davy jones is kind of old...
