I'm betting right now that we see an Aliens Warrior maquette. I'm also betting that the pose is going to suck so bad that I have to seriously wrestle with the idea of actually buying it. I hated the A3 pose so much, I turned my back on it, especially since the display piece at the Con that year had a crack in the dome.
I also have high hopes for a Predator 2 maquette, but I'm not too sure that's happening this soon, especially if they show off an Alien.
They say in the last Ask that they have TS PF stuff in the works, but I'm not sure there's anything from that movie I find PF worthy of buying, and I don't see it being revealed this soon, but who knows.
As for Hot Toys, I think we'll get Gort Pred or a Pred with that mask included. Maybe we'll also see the battle damaged edition Pred 1.
