So, what do we know we are getting/maybe getting for next year? From what I have read, this is what I have seen so far
Usually NECA releases 3 waves of 3 figures, so going by that we already know that series 7 is Concept '79, AvP Warrior and Grid Xenos.
As far as basic figures go, So far we have seen a prototype of the Alien3 WY Commando, we have confirmation that Alien3 Ripley will be made, and that we will get a Smartgunner in series 9. If including the Smartgunner that we know is in series 9, if the Ripley and WY Commando are released next year, that leaves 3 slots open. Of course, it is possible we may get a 4-figure wave like wave 5, but I'm thinking the waves will just have 3 figures each.
Also either confirmed or under consideration by NECA are: chestburster has been confirmed for next year (but unknown how it will be released), Queen/super Facehugger sculpt has been seen, and prototype 1/4th Warrior Xeno has been seen. Randy also hinted at a possible Warrior Alien army-building 3-pack set for next year as well. I may have forgotten something though...
So, given this info what figures do want or expect to see? I myself expect a bit more "Aliens"-themed figures, as it is the 30th anniversary, so hopefully more Marines aside from the Smartgunner are possible, and a Ripley in her jacket as well. i suppose the need could be fulfilled by the 3-pack (and by the recently released black warrior) but I would like to see another basic Xeno Warrior re-release, maybe a Brown re-release or some other color. I know Lambert had been rumored and possibly spotted in NECA office photos. As well, i know they said we may see the AvPR Predalien in '17, but they may release the AvPR Warrior next year.
