Fueling the fires of expansion rumors, it seems a brand new trademark has been filed by ArenaNet and NCsoft. As dug up on reddit, there's also a new logo but little other news for now. Could this be the long-awaited expansion to Guild Wars 2?
Imgur Thread with Pictures of Filing
While there's little other information to be gleamed from the trademark filings, it's pretty clear that this is something much bigger than just another Living World update, as they haven't done trademark filings for those in the past.
Season 2 of the Living World ends today in Guild Wars 2, and in just a little less than two weeks the big PAX Panel at PAX South should finally reveal to us all what ArenaNet has been working on alongside the Living World updates.
