Until Dawn 2? It can't have the same characters in it.
I think that if they make an Until Dawn 2, it obviously can't have the same characters and setting because of the open ended aspect of the game, so hopefully they dont stck with the whole Wendigo thing. Hopefully they have something completely different.
Idea: Set the game in the geographically isolated logging towns up in Northern Washington state or Alaska and have the creature be Werewolves or something similar. They can still keep the Native American, "sacred ground" angle on it. The final climax can take place in an abandoned logging mill. Those places are creepy even when they are open.
