This is a highly suspect rumor, so please give it plenty of salt. Much of it though does appear rather logical. This latest bit contains both the original post and added information + a bit about where helterskelter got the info.
This is a rumor, please take with added salt.

More rumours about the 8th edition, not how the rules look but the background 🙀
Look for the plotline of 8th Edition to wind it’s way to Mars, seat of the Adeptus Mechanicus.
Upon it’s surface the Emperor has laid a grand plan millennia in the making.
Which only his returned sons can complete.
An ultimate tool to cast down the Ruinous Powers.
Another hint that the Primarchs are back
A word on where this is coming from via helterskelter
You can, i have an associate, and we're part of a private FB group, he posts what he gets from his sources, whom he refers to as his "spies"
Also this is the pic that people have been looking at for the January White Dwarf speculating that this is Abaddon with the top note above the blocked out image.
