I don't think many were affected by Will and Elizabeth's absence. Like it or not, both actors had stated they didn't want to continue, and so the franchise had to continue - with or without them. And it's a bit unfair to say that their absence was why On Stranger Tides didn't live up to some expectations, especially when some considered it a positive aspect of the film. In fact, despite facing critics, many fans did at least like the film, considering it the second better Pirates sequel(though some tie it Dead Man's Chest). Plus it made over $1 billion, a feat not easily done. On Stranger Tides may not have done well critically, but it has to be a reason other than Orlando and Keira's departure, as the film did work without them.

Now getting to the matter with what official information we have... The only one who has the slightest chance of returning at this point is Orlando Bloom, because of his expressing interest publicly. Unless Keira Knightley has expressed interest in returning (which she hasn't), she has zero chance of returning. Having said all that, I wouldn't get my hopes up too high. Just because one actor expressed interest in returning doesn't mean the couple will return. Chances are, neither will return at this point.
