Hyped on all three counts here. Gillis (through ADI) is coming off of some really killer work on Prey, and Weta and Legacy are some of the best in the business as well. And they all have art from Dane Hallett at their disposal that they're working off of, as well!
My one hope/concern, on Weta's end, is that assets aren't shared between Romulus and Hawley's series. I'd love for each project to get to design their own Aliens from scratch.
