Survivor is going back to its roots. The fourth installment of CBS's reality franchise — Survivor: Marquesas — will take place on the South Pacific island of Nuku Hiva. The show's first chapter was set on the South Pacific island of Palau Tiga. (We can only hope it's that good.) Survivor: Marquesas will debut on Feb. 28. Meanwhile, Survivor: Africa's two-hour finale airs tonight (8 pm/ET), followed by a live reunion with all 16 players.
