Am I the only one who thinks the ending wont be generic to everyone? (So there will be several different outcomes for the end). I have a feeling the last episode actions will vary slightly depending on what you have done through the whole series and choices you have made.
I honestly wouldn't be surprised if the groups fate would remain unknown, or certain characters die, or it is unknown whether Lee dies etc. With so many possibilities it would give the players their own views on what they believe would happen as well, thus leaving episode 2 open for a brand new story.
