With rumours of a fluff shakeup/advancement for 40k happening in the future I'm just curious what kind timeline advancements people would like to see? Do you want to see something radical or something more subtle?

(predictably) I'd love to see the proper introduction of enslavers as a new ultra-lovecraft themed faction and a new great threat with a second great enslaver plague thrust upon the galaxy with all the races including chaos fighting them. I'd give the enslavers a pantheon of lovecraftian deities that live in the warp and are older than the chaos gods. It's awesome in my head, at least :P
