Hints, leaks, what's to come?

So, KI has been giving away some hints and tips on future content supposed to come out this month, but what could it be?

The Ancients, who are them?
Also, the background and Bonnie's tier suggest that this quest is in Skull Island, but could the Ancients be P101's version of the Titans of Greek Mythology?

What's this at the Musketeer Roost? That looks like a boat that will lead to that giant eagle holding a giant arena (coloseumn) on it's back, but, is that Ranked PvP? Or better, Ship to Ship Combat??
So many questions, but fear not because I think we will have the answers in a short time...
