The Predator in the center with the cape is not the Predator Elder from P2, but the Predator Elder that makes a cameo appearance at the end of AVP.

From the looks of things, he's wearing his bio-mask, which was never worn by the character in the film outside it appearing on his shoulder as a part of his armor. I hope that the mask will either be removable, or that he comes with an alternate head to recreate that look, as while I didn't care much for the look of the Elder in that film, I did like the way he carried his unique looking mask like that.

As for the other, possibly new Predators in the shot, I have the feeling that they'll just be additional temple guards or ancients. Either that, or the two Predators that were tasked with taking away Scar's body at the end of the film. Wolf could also be a possibility just so they can get him out of the way without creating an entirely new series of Predators (since he technically would fit in with the first AVP film considering AVP:R is supposed to take place moments after the first one ends,) but his armor is entirely different from the rest of the AVP armor sets, in look and design.
