The lip sync and general facial animation is well beyond anything DontNod has managed in their last 3 games, and that's with their own relative improvements (sans Twin Mirror which was actually a step back from Tell Me Why). Deck Nine just have a way better grasp of rendering subtle, believable, emotions in their characters.
This isn’t Life is Strange 3. Just like Life is Strange before the storm wasn’t Life is Strange 2.
Since DontNod have ended their partnership with Square Enix and full control over the series has been given to Deck Nine, it basically is LiS 3, in that it's the new mainline entry into the franchise. They're no longer relegated to spinoffs.
I hope it will be a little longer than Before the Storm.
They've been working on this game since 2017 apparently so it damn well better be, lol.
