The AvP guy seems to be indicating he's not directly referencing the AvP films.
200 year lack of contact is speculation, though.
No, it isn't. Saying it's "speculation" is a classic handwave.
That doesn't mean you can't have Alien encounters though. You could have a group of people who are way out in the middle of deep space who encounter the Aliens (and Predators and Engineers even), and are completely cut off - either on a ship incapable of going to hyperspace, or on a planet they can't escape from. The cut off aspect means it doesn't conflict with Resurrection and
it returns to the feeling of isolation that pervaded the first film (which is what they seem to be going for anyway).
It could be an ongoing series with the main purpose surrounding the protagonists attempts to get back to civilisation or at least warn civilisation. Of course the obvious danger being that it could become Gilligans Island, but there you go.
And there are other ways you can have isolated Alien encounter stories that no one in WY or the USM could know about. But having too many of that sort of thing starts to strain credibility after a while.
