I would guess it is because Arekkz or Gajin have commented that in their videos. " Makes me think though, that the heat is coming from some kind of Volcano nearby. That might be the next area they reveal, hopefully by December." If you look at the background area at the end of the PGW trailer where the unknown monster is, it is 100% a volcano, i would guess they will reveal it at Playstation Experience.
