One of the concerns about a new race being spotted is that models were seen and misinterpreted as 40k models but were instead for the Age of Sigmar. Here is a very small follow up.
Again, lots of salt until we get something a lot more solid. This is very much a rumor at this point, and nothing more.

One of those rumours without proof I'm afraid but got it from a close contact that squats are coming back, little bit steampunk, to 40k. Bonkers but true.
All I have currently is they are quite steampunk in design, think blimps and jump packs with a new jump pack base design.
