Currently after completion of the boss battle (before it went down), there were no further quests. We just received a message that said expansion coming soon.
There was a review or something that stated the expansion will come out during the summer.
I'll search the forums and see if I can find the link to that article

This is the statement we're all banking on:
This summer, Goslin said more story will be added to the online world, including elements from the third Pirates film, At World's End.
