I'm not surprised. NECA's schedule's are frequently late and/or all over the place. Mind you, there's so much 'ALIEN' related stuff coming out from them. There's also the 'PROMETHEUS' Lost Wave content and 'ALIEN: Covenant' figures along with other merchandise for that movie. So, they have about 20 items on the cards right now. ...and that's just the 'ALIEN' items without considering their many other licences.
It doesn't worry which series is next, actually. Looking forward to it all. Can't afford any of it. lol.
