I just finished the Fallout show yesterday and it was so good that it filled me with a lot of hope for the Warhammer shows. I wouldn't mind them doing a adaptation of existing stories as there is a certain series I could see lending very well to that idea (Gotrek and Felix) but I'm assuming we'll see a 40k show first, from which I hope they would maybe take some inspiration from ASTARTES, make it very self contained and really show the weirdness of the unvierse. I'd also like to see a high budget animated show in the vein of Invincible coming from 40k, maybe more xenos focused. The warhammer+ shows are of questionable quality, not to be critical of the animators themselves as I'm assuming they didn't have a lot of resources to work with. Otherwise I'm very hopeful of what will come from this collaboration.
