Re: UPDATED! Hot Toys - MMS 106 - Alien - BIG CHAP collectible figure
They may, but that's where their "value" comes in, lack of options, on their own, people probably didn't find much desire for them, but may change their minds later because of lack of options.
HT seems to focus on what will sell very well today, right now, on it's own value to people and not the lack of options type sales. Even then, there's figures at times it doesn't quite make sense why you never see them as they seem liked they'd be as good a seller as the other figures, like Barbossa in the POTC line. Look at their lines though, and it's pretty obvious.
IRON MAN
Mark I, Mark II, Mark III, SDCC Ex. Mark, Mark III BD (nothing but variations of the hero, not even the villain)
THE DARK KNIGHT
Batman Begins, The Joker, Batman TDK, Joker BR, Two-Face, Joker DX, Batman DX (only the 3 mains)
PREDATOR
Dutch, Billy, Predator (and really, I don't get Billy, by HT standards, Dutch would have been enough)
ALIEN
Dallas, Kane, Big Chap (and if it weren't for the unique suits, I doubt we'd even have Kane and Dallas)
