Did we already know about the contracting of Syd Mead to design the interiors, and the hiring of two Battlestar Galactica senior writers? And apparently there will be gameplay systems to represent every bit of equipment we see the marines using in Aliens. Combine that with a pretty engine which looks nothing like Unreal Tech 3, and it sounds like a seriously promising title...
As for the Nostromo, I'm betting on either a multiplayer map, or the Nostromo's class of freighter making an appearance in the game (like the Ferarco in AvP '99). Perhaps as a derelict, or something like that.
