On topic though,
we have had too much spoilerish info as opposed to clear, defined promo pictures and/or stills...
Knowing a kid will get a chestburster out of him, how most of the characters will die, or even how the Predalien looks and how he and Wolf kill eachother is info we could well do without...
There is a difference between info we need to know to see if the movie will be worth watching, another is spoiler info that will make those scenes lose the momentum they would have if unexpected...
So, I think we already know too much about what we should have known less, and an awful less of what we should have known more, namely story elements...
or maybe what we've seen is what we will get story-wise: Predator ship with facehuggers onboard crashes, the huggers escape, impregnate a father and a son, then they spread until they infest the town, the military gets called, they fail on the ground, then they drop a bomb,a nd the survivors have little time to flee the town before it is destroyed... This is human-wise... Aliens and Predator-wise, Wolf lands here after the Predator ship crashes, with the mission to contain the threat, namely, kill all in his path... he fights his way through the infestation until he gets to the Predalien Queen, and after a violent brewl, the PredQueen impales Wolf, but he manages to pierce the PQ through its head...
These are the broad strokes of the story we have seen so far, both in the trailers, pictures (as the Predator keeps losing equipment in the shots) and info we have been getting so far...
So, we already have the story layout, what we don't have is the sub-plots, dialogues, acting and such...
So, I think we know more than enough already to make informed opinions as to the appeal the movie has or does not have or will have...
So, we already know too much...
