Also, I'm really looking to seeing how they'll answer our three year long question about Nerissa/Faith and what story they'll come up with for Season 2.
I'm pretty sure that, during one of the AMAs when TWAU was brought up, someone from Telltale staff said that if there was ever a sequel to TWAU, they would not continue the story from S1 and leave the ending ambiguous, with hypthetical S2 being a brand-new detective story or something.
My next thought - Nicole Martinez was in the announcement video. She was on the writing team for S1 (I'm 100% sure she wrote the finale, don't remember if she had a full writing credit or just an additional writing stuff in other episodes), so if I am to buy Season 2, she must be a lead writer. If they'll put someone new in charge or - God forbid - that Adam-whatever-his-nave-was who wrote most of ANF, then it's an insta hype killer.
Another thing - some of you probably won't believe me, but the other thing that came to my mind was... Game of Thrones S2. I mean, look at it this way: - TWAU ended in 2014, no sequel announced; it's the middle of 2017, sequel announced for a 2018 release; - GOT ended in 2015, sequel announced immediately; it's the middle of 2017, the game is nowhere in sight; - Minecraft ended in 2016, sequel announced last month, it's already in release.
But most of all... with where Telltale is now, I feel like this is clutching at a straw. It turns out TWAU is the second most profitable franchise in the post-TWDS1 era and they're simply going back to it. If - I guess - sales of other titles weren't so underwhelming, Telltale would never go back to TWAU.
To sum up - am I hyped? Only barely. Until we find out who's on the writing team, I'm cautious.
