I'm not saying this for fun, but I'm only stating facts...
 * 1) As I said, Will and Elizabeth's story is over. While it is possible they could make a book or short film relating to "trying to set free Will", it is highly unlikely that either Will or Elizabeth will return because of that.
 * 2) While some may disagree, On Stranger Tides did work pretty well without Will and Elizabeth. There weren't many fans saying we miss Will or Elizabeth(particularly those here or at KTTC forums who are actual users).
 * 3) Both Orlando Bloom and Keira Knightley maintained that they were ok with not returning in the films. While Knightley has said nothing(sticking to her word), Orlando gave his view on "if he was offered", he would return. But as it's nearly impossible to bring Will back without messing up what was established in AWE, I wouldn't expect Will to return.(especially if it's an issue of "if you have Will, you gotta have Elizabeth too" and vice versa).

The way I see it, as I stated above, AWE ended their story perfectly...and so they aren't really needed in the films at this point. And like some fans, I prefer it to stay that way. Besides, it would make more sense in bringing Philip and Syrena back(whose ending was left ambiguous), compared to bringing back Will and Elizabeth(whose ending is pretty much laid out, thanks to the AWE post credit scene).
