It's always been here, hale and hearty.
Something I'm very curious about, is whether Games Workshop will take the chance to delve into more areas of the Warhammer World.
Albion, Vampire Coast or Cathay, for instance.
Nippon in the 1980s, not seen in miniature form ever since.
This could be especially doable if the new Warhammer Fantasy take is more limited in scope than the vast army books of the past, with all their demands for miniature kits. The army book format in and of itself became a creative straitjacket for the GW studio. In the 1980s, they were free to release a handful of new figures whenever they felt like it, and thus explore Nippon, Halflings, Norsca, Fimir or a plethora of monsters with small investment of resources. In the 1990s-2000s, they were increasingly bound up in the demands of the army book threadmill. If they wanted to release something new, it had to either be a complete new army, or just something small on the spin-off side such as specialist games and Dreadfleet (for which the market wasn't good in those days, or at least marketing under Kirby wasn't up to the task) or summer campaign miniatures such as the Hellcannon, Middenheim and Albion miniatures delving into niche concepts.
Kislev during 6th edition: A mini-army, later unsupported.
We did see Dogs of War and
Chaos Dwarfs as a small new army in the 1990s (unsupported after 5th edition up to 8th), and a small army for Kislev in 6th edition, unsupported thereafter. Warmaster sported Araby, but Warmaster was not a great hit. Ogre Kingdoms was the one new big army, or one of two if you count the Daemons of Chaos' expanded range, and it needed an entire miniature range.
Chaos Dwarfs: 1990s army, yet left out in the cold for most of Warhammer Fantasy.
Then there were fun thematic armies in White Dwarf, such as Kemmler's Barrow legion, Vampire Coast, Clan Moulder and the Gnoblar Horde. Building on existing modelling ranges and often requiring conversions: Which was part of the fun, for sure, but ensured it stayed a tiny niche and opened up for small companies to produce models GW weren't. This problem of inviting in the small competition to open new niches was much exacerbated when studio designers during 7th edition introduced new units in army lists which did not yet sport official models, such as Forsaken.
Dreadfleet: One last exploratory hurrah before the End Times.
This commercial bind ultimately put dampeners on Warhammer's creative potential: It is huge, and can be explored to much greater extent with a more limited setup than army book-threadmill WHFB of old. But ultimately GW would want to produce models for anything peripheral they delve into, and that mean they may well shy away from introducing more things on the periphery of the background, to not give competitors possible bones to snatch.
Fimir: A weird 1980s creation because the CEO wanted Warhammer to have its very own fantasy race. Resurrected lately by Forgeworld after decades of hibernation.
So there may be little in the way of brand new additions to the glorious setting, such as Inca Dwarfs in Lustria, fantasy Songhai and so on. And there may potentially also be little in the way of covering already existing periphery stuff such as Khureshi Nagas, Albion, Ind, Norsca and so on; this obviously depends on commercial success, how limited in scope the new game and miniature ranges will be, and on budget or will within the studio.
This is a long-standing limit to driving the creative potential of Games Workshop's own grimdark, historically based, classic fantasy smörgåsbord setting to the hilt. It remains to be seen if and how GW will tackle this obstacle.
