Had a browse round the GW (web)store.
Looks like six out of seven* Empire** units and characters have become Webstore Exclusives. Only melee State Troopers (Freeguild Guard), Greatswords, Battle Wizards and the General remain on the shelves. On average, one third of Grand Alliance Order are Web Exclusives, so the ordinary Humans are really being pulled from the shelves.
My personal thought is they're slowly being withdrawn - which likely mirrors sales, knowing GW, but also the future visual and mental image of the AoS setting.
There have been no ordinary Human concepts introduced during AoS, whereas we are seeing new concepts and sub-factions for Dwarfs and Elves. Also the Lizardmen/Seraphon, Goblins/Grots and Skaven are mostly Webstore Exclusives, as are all ex-Beastmen (Bray- and Warherds). Something going on with the Seraphon. They seem to be in the process of being lumped into Celestials with the Stormcast Eternals.
It will be interesting to see if new kits replace the ex-Empire, or if ordinary Humans as a concept will be brushed aside from AoS setting. Possibly only the superhuman Stormcast (Sparta! Marvel!) will remain. After no more Bretonnia and if no more ordinary humans fight in the setting, the feel of the setting will be totally different from the Old World***, which clearly was a Human setting surrounded and invaded by the hostiles.
My personal thought is that a lot of old WHFB and general fantasy familiarity - with a Human vantage point within the setting - will be vanishing within a year or two. Not a revelation really, just the continuation of where AoS has been heading all the way.
Edit: Not meant to be rumor mongering. Just my own thoughts, thought aloud.
*24 out of 28, counting double kits as doubles
**Humans without the Stormcast Eternals: Collegiate Arcane, Devoted of Sigmar, Free Peoples, 4/10 of Ironweld Arsenal
***the Old world itself having strong roots in Tolkienesque fantasy, Elric and real world history.
