The crowdfunding site is live-- minimum pledge for a copy of the game is $29, or $24 if you pledged at Fig.co before for Wasteland 3. ETA is Q1 2018 but don't expect them to make it.
Gameplay-wise it looks like more of the same, which is perfectly fine by me! Greatly improved graphics, yadda yadda yadda. They also added NPC schedules ala Ultima 5.
I pledged instantly, and if you want to support great PC CRPGs, you should too.
