If Legacy is working on the effects, that's definitely good. Hopefully they can fix some of the problems. Stan Winston's predators looked the best but there were times when the rubber suit was obvious (the medkit scene, for example) and in Predator 2 some of the animatronic effects for the predator face looked a little strange in closeups.
I actually don't have too many nitpicks with ADI's or KNB's work. The suits did look a little too bulky at times. They also can't seem to get the predator faces right (one exception is the AVP Elder Predator which looked badass). It's particularly noticeable with the classic predator, as you can directly compare. Wolf and Berserker are great, though.
If they can at least top Wolf or Berserker, because that set the bar for the sequels (the original is unlikely ever to be topped nor P2).
