This is circulating and its originally from Tabletop Welt (https://www.tabletopwelt.de/) some time ago.
Im not going to go through the rings with each bit here as it seems that some of this at least is not going to happen... like Gorkamorka. Who knows though, and I had thought we would see Orks much sooner than this.
Please remember that these are rumors.
A big thanks to Warhams-77 on Dakka and Miniwars for bringing this up for us to see.
