Well, If my memory serves me, Predator 2 and the AVP movies were virtually ignored by Predators. And it is assumed that Alienkamp will ignore Alien 3 and Alien R (although with this last film we're not 100% sure). In Prometheus, Ridley Scott told us a lot of confusing things before the premiere. And at the end of the day the film ended up being an untraditional prequel.
But the point is that every time I see someone saying gimmicky things (instead of giving us a clear and simple message) I get the impression they are trying to do something unconventional with the franchise. Which is not necessarily bad, Don't get me wrong.
