I don't like the "milking" tactic either, but I guess if they hadn't made all the AvP dudes and sold them as well as they did, they might not have taken a chance and made that bad-ass P2 Elder! The AvP Ancients were basically sort of an afterthought, the bio-mask being the only difference between them. To me that was the most blatant case of "milking". The BD Scar was probably intended mainly for the Hong Kong fan boys originally, so I don't know if it quite qualifies as milking or not. That said, I don't condemn Hot Toys for getting what they could out of the molds their first time around. I figure it greased the wheels for the even better figures they've released since then.
How much is left for them to milk from the P2 license, unless they try to make some of the Lost Hunters? I caved and ordered the Sideshow BD P2, only 'cause I want the medkit and other accessories (which they could have included with the first figure if they'd wanted to). That's enough for me.
I've got my Wolf and Predalien coming, and that's all I need from that movie. The only other Predator I'd want after that is the original, which will hopefully be announced some time next year. There's talk of making Dutch and some of his team, but who knows if that will really happen or not.
