Nice. 6 fingers is a strong indicator we'll at least see a return of the original design to some degree. Mind you, in 1979, Fox would not even have permitted this much of the Alien to be made public. Back then, the human characters and interiors/exteriors of the Nostromo and derelict were easy to come by; but prior to the film's release on May 25th '79, the creature was completely unknown and Fox were extremely secretive about it until the movie was released. You really had to dig hard through the pages of magazines of the day to find a single Ridleygram of what the Alien looked like.
How things have changed since then. I fully expect we'll see images of the inevitable action figure(s) well before 'ALIEN: Covenenant' is released.
