Yeah, Neil Druckmann confirmed that Ellie is the main character for this one. He said that part one was told from Joel's perspective and that part two will be from Ellie's perspective. Whether there are parts you get to play as Joel or someone else we probably won't know until we play the game.
And is that a female that is dead in the bathroom as Joel walks by? For whatever reason the first Last of Us had no female Hunters or Fireflies. Hopefully that changes for the sequel. Getting annoyed at games that don't feature a single female enemy throughout the entire game.
Oh, and Neil said that Ellie is 19 in this game, by the way. Needless to say, I can't wait to play this one.
