Pretty big spoilers dropped by VF, IMO... now we can confirm that the character formerly known as Rose is really Maz Kanata (played by Lupita Nyong'o), has Anakin/Luke's saber, and her castle is attacked at some point by Phasma, played by Gwendoline Christie.
Anyone notice the dude in the picture of the space pirates wearing an old Stormtrooper helmet painted black? Right to the left of the red dude. I kinda wish there were more "classic" aliens, or even PT aliens thrown in, but it's all good. Just from that picture alone, I can tell this castle scene will feel more like the Mos Eisley Cantina than that stupid Coruscant bar from AOTC.
