The Witchdoctor's Lab- The Mystery Deepens

KingsIsle and Pirate101 released a vine today showing a glimpse of a mysterious chamber. https://vine.co/v/MaEBFqpKpvz The top of the vine video has "Witchdoctor's Lab" on it with the caption "What kind of #Hoodoo is being cooked up by #Pirate101 in the Labs of KingsIsle?" What does this mean? Is this a new crafting system? A rework of Vadima's lair? A preview at new houses? I believe it is either a peek at new class housing or a new crafting system. How about you? Feel free to share your thoughts.
