sorry if someone posted this before but just think that it is very unlikely EVERYONE dies. I personally think one of Christa and Omid dies (almost defenitely Omid w/ his leg). Ben will risk his life for someone.
Overall the final group I have is Clementine, Christa, and Kenny. Ill actually be surprised if Kenny dies but we'll see.
Edit: really surprised at how many people think Ben will survive. I dont see TT making the extra effort to keep him alive for those that killed him.
