That is a possibility. But I do think they were working on it (post-beta) at some point. I also don't see the need for "Davy Jones Cursed Blades" if they weren't going to add more to the Ravens Cove Quest (and they did say they were working on a "Curse of Doom Storyline" which is probably something kraken-related)
