Actually, time has told-- it is official as stated by Ian Whyte (AVP, and now AVP2) and the studio designers as well as the Strause brothers that they have gone back to the original PREDATOR design. This Predator will be athletic, much like the first two Predator films.
So yes... we are looking at the first movie design.
I would like to see aliens born from different animals. In Alien 3 the alien grew inside bull or cow (Well in the book and special edition, dog in the std film. If you haven't seen the special edition Alien 3, its a huge improvement of the cinema release and follows the book much closer.) so it was slightly different to the ones from humans. It would perhaps be good to see aliens that’s have come from humans as well as other animals.
However all we really need is aliens and predators fighting, and humans as cannon fodder, (Its all we’re good for) Oh! And lots more gore
