I just found out about this game a couple weeks ago myself and have been watching stuff on it since. Seems like it's trying to pick up the ball that Bioware keeps dropping and I'm looking forward to seeing if they can manage. It's weird how little attention this is getting for how ambitious it seems to be. There have been a few games like that lately that I've come across.
Are you sure it's the same people as Vampyr? I know it's the same publisher, but it was DontNod who made Vampyr (same studio that did Life is Strange), and I don't recall anyone leaving them and going to Spiders (their most recent games were Bound by Flame and The Technomancer I believe). They are both French developers though so it's possible.
