i dout that they will put sj in next game, it is possible that they will, but only as a reference to alien, they probably wont divulge any new info about them, cos they could be leaving it to the movie writers to come up with their own thing. if you check youtube for avp redemption video, it is a good idea for the sequel to avp3 as it starts similar to the way avp3 finished minus the part about why the pred is there.
