I've heard that rumour too from GW staff. He was pretty up front about not having any solid information one way or the other, but given GW's recent management history I don't find the idea incredible in the slightest.Silentpony said:
I mean, moving the setting forward in time is one thing - I can get behind the idea of story progression. But Age of Sigmar didn't "progress the story," it set it on fire and hurled it into space. If they do the same with 40k, we'll end up with...I don't know...Marneus Calgar piloting a mecha-marine that is piloting a larger mecha-marine that is piloting a spaceship the size of the Moon [https://en.wikipedia.org/wiki/Gurren_Lagann].
And the Blood Angels have replaced their power armour and bolters with blood armour and bloodters firing blood-bleed bullets.
