Anyone read the article on io9? Sounds pretty interesting, actually, though GOD KNOWS I've said that before and been wrong.
They've all but said they'll be ignoring the AVP movies, and the Alien comic is going to be based more on Alien than Aliens. FUCK YES.
Only potential snag I see is that all of the titles (yes, even Prometheus) take place int he same universe. That's not necessarily a deal-breaker, but the potential for stupidity is astronomical. If they can find a way to pull this off, more power to them, but... Eh.
