Right about that. NECA said there will be more USCM but not soon, so there's more rumor control than any fact.
Let's not forget these could include ACM Marines, which could compensate Aliens Marines actors' likenessesses.
I mean, everyone needs a smart gunner around here, but what if Drake or Vasquez can't be made ? Better than nothing if we get an ACM smart gunner. For instance, Sgt Windrix wasn't a bad figure at all, features some cool stuff and adds a touch of renewal.
