There's no way Hot Toys will produce all of the Marines. But, i'd say there's a reasonable chance Hicks will be re-made. Maybe Hudson and Vasquez.
Sure, all other licenses are second-fiddle to Marvel, but I don't see Hot Toys abandoning their Alien/Predator lines anytime soon. (Even if their 1/4 scale announcement remains unfulfilled 4 years later!)
Plus, the Marvel stuff will die down eventually, or another company could come along. On the positive side, we're getting a new warrior, a powerloader, two Ripleys. Not a bad haul. Works out nicely for me as my fig collection has been streamlined to just AvP/Terminator, pretty much.
Plenty of cool statues on the horizon from CoolProps, HCG, Prime1 and Chronicle, plus I plan on going back to the T2 figs and the Terminator Salvation line. I've also got a few more Preds to pick up. Maybe the older HT Aliens if i'm feeling brave. Plenty to keep me occupied!
The lack of Prometheus figs was disappointing, but I'd bet that we'll see more AvP stuff in the not too distant. Chopper, Grid, Lex.
