I wasn't saying there won't be an AvPvE fight, I was referring to Sebela's answer to your fan question about the Engineers creating the Predators. His answer made it seem that they won't be delving into the backstory of the Predators and Engineers to any great degree. That's good, in that we won't get something awful like "Engineers created the Preds!" But bad in that it could mean we don't get much backstory at all.
As for the PredatorS issue, you're right about most sites not knowing their heads from their butts, so I'll concede that point.
