Rampant trolling speculation would include the possibility that we will see Emet-Selch walking around and be very surprised, and then a couple of patches later we learn that it was actually one of Emet-Selch's Solus Galvus clone bodies.

Even more surprise if we learn that this clone body is being piloted by Varis, who Resonanted himself into that body because he was still salty about Solus telling him that his "body" was somehow disappointing.

(It's not going to happen.)
