The Old World is something that of older players remember with fondness and is often a more familiar setting type than the current Age of Sigmar, which has a ton of appeal. Here is some rumors giving us some insight into when we might be expecting to see the anxiously awaited return to the Old World of Warhammer Fantasy.

The Old World
I have some (not so positive" Rumors) about Warhammer - The Old War...
As said in an earlier mail, there will be no miniature previews before mid
2022.
Model Ranges are already in the Work, but the most progressing Part of the
Reboot is the Backstory and the Freerooms they have because the different
timeline.
Early Factions for the Game will be no brainers and all time community favs
like the Empire, Orcs and Goblins, Dwarfs and Chaos. Those factions are
focused the most but others are in the work, but do not expect Cathay or
other niche factions too early, those will need years after the reboot to
come to light.
Release could be Summer 2023, but that Date isn't finally set. Covid
brought more trouble for GW than everyone believes...
New Edition Timelines
They're also internal changes for Warhammer the Old World. The main Studio
is more involved in this project, which was the idea of the oldest Studio
Members.
Also the established release shedule for GW in the last years is mostly
obsolete thanks to Covid: They can't no longer bring new Editions every
three years.
