Probably the Black Pearl, or a way to unbottle it. I think they would probably lose a lot of magic if they just opened PoTC5 with the Pearl freed, and some ambiguous reason behind it.

I don't think it'd be too bad if they mixed Jolly Roger in all this, especially if they gave him a good character (if you've watched Guy Ritchie's Sherlock Holmes, I'll tell you a Blackwood-kind character would be beast) and made him cooperate with Jack to get the Pearl back. That'd be a twist upon a twist.
