yeah predator 3 is in pre production. To have an AvP movie aliens fans sacrificed the hopes of cameron returning for another sequal to the alien movies. He was very interested in doing a new story on the aliens that would indirectly tie into the previous four making it a sequal. After AvP was confirmed, cameron said there is no point for him to make another alien movie if the aliens are going to be in there own movie already. He still says if the project would ever get under way he would like to have a hand in it some way, maybe producing.
Im looking forward to AvP but id rather see james cameron take on another sequal to the aliens than Paul anderson's AvP any day. Look at resident evil, now look at Aliens. See my point. oh well i have had time to heal and calm down so i still look forward to this movie and have some faith in anderson.
