The situation in the galaxy in the 41st millennium is certainly in flux right now. The Gathering Storm series is showing that new things are afoot and it might actually have some lasting impacts on the story. The next book, Fracture of Biel-Tan, is up for pre-order now, along with some new minis to go with it.
From the website:
Fracture of Biel-Tan is the second book in the Gathering Storm series. A 136-page hardback, it introduces the Triumvirate of Ynnead – The Visarch, Sword of Ynnead, Yvraine, Emissary of Ynnead and The Yncarne, Avatar of Ynnead – and chronicles the desperate battle to determine the future of the Eldar, and the uneasy alliance that will potentially dictate the fate of the galaxy.
