I'd like to point out that while Pirates 5 in development, there is absolutely no official evidence of a Pirates 6(neither Disney nor Bruckheimer announced it, so I take it as pure speculation).

And the way I see it, it is pretty likely that all the sequels to CotBP are sequels(given that the timeline of where each character is and what they're doing). However, if this ends up being a trilogy(or at least OST and P5), I would think that these would be standalone type stories: Jack searching for the Fountain of Youth in OST and some new adventure in P5(whatever it may be).
