According to a representative of the show, Junhyung and Doojoon are currently discussing the final details with the producers. While their appearance has yet to be officially confirmed, it seems highly likely that they will join the show.
Also a member of BEAST, Kikwang appeared on the Solomon Islands special of the show that aired last fall. He received great attention for his fearless and positive attitude after joining the show despite his severe seafood allergy, which fortunately did not act up in the jungle.
Meanwhile, the cast members will depart for Samoa in October, and the episodes are expected to air after the currently airing Nicaragua special ends its run.
