I've finished Book 14's main storyline quests and acquired three pieces of Marco Pollo's Map so far. There's 2 more Map Pieces out there, yet to be discovered, and 2 more in the Armada's possession, which will be taken back from them someday soon. I await to see Book 15's preparation to the Test Realm real soon, as I'm itching to find out who "G" really is, and how he knows how Kane can be taken down for good. However, with Deacon and Rooke down forever, I'm certain Kane and the Armada will go to further lengths in the race for the remaining El Dorado Map Pieces, and to try to take the 3 pieces away from the Pirates, regardless of any means, especially the remaining Elites themselves, because I know the next stealthy trip to Valencia is going to be even more difficult than the last time. I'm hoping Book 15's wait won't take way too long, because I aim to complete Special Branch's mission and figure out the Armada's "Grand Design" is about very soon!

No telling how long it will be.

Their first content upgrade with 2 new worlds, was in itself unprecedented, and based on some of KI's various team members comments on that undertaking extremely arduous, I have a feeling they wont be targeting that large of a chunk again. Wizard101 would get roughly 1 major update a year, I expect Pirate101 to be similar.

Wizard101 is 4 years in the making, Pirate101 is only about 1 year old now. ;)

Kingsisle was very generous just to release TWO worlds instead of one. It's going to be a while until another comes out. Just think about how hard it is to make a video game so just wait.

Yes, very generous, but it was also the largest update, by far. And they weren't kidding. It was a huge content update! One that tops any of Wizard101's previous content updates, even the then-latest updates.
