Apparently this is not a hoax, and GW has strung us along enough. I'm sure many of you got the GW fanboi e-mail today about the Incoming Grey Knights.
Apparently Grey Knights are shipping in April (about time)
From the GW Atronimican site:
— Article by Adam Troke
As the Emperor prepared for his final confrontation with the traitor Horus, he granted one final gift to Mankind, a safeguard and protection against the horrors of the Warp - the Grey Knights. A brotherhood of warriors as elite as they are secretive, the Grey Knights are a shining line of silvered steel that stands between humanity and the Daemons of Chaos.
Trained as the mightiest paragons of mental fortitude and martial discipline in the Imperium, the Grey Knights maintain a vigilant watch for daemonic incursion, responding wrathfully against the scions of the Dark Gods, and those who dally with them.
Clad in baroque Terminator armour and wielding powerful weapons such as storm bolters and Nemesis force weapons, the Grey Knights tear through the enemy, unleashing an onslaught of psychic powers and sorcery to sunder the foe.
The Grey Knights are an unstoppable force, the manifestation of the Emperor's will, valiant warriors who willingly sacrifice their own humanity so that Mankind itself can endure.
This April Games Workshop releases Codex: Grey Knights, alongside a comprehensive range of fantastically detailed Citadel miniatures. Although details are being kept firmly under wraps for now, you can expect an exciting selection of plastic kits to enable you to build your own Grey Knights army.
Over the coming weeks we'll be releasing more details both here on the Games Workshop website and also in the pages of White Dwarf - to ensure you're the first to get the news, make sure you subscribe to the Games Workshop newsletter and keep an eye on the What's New Today blog.
This better be good. I'm saddened by the loss of my two codexes, and I hope GW gives as much variety back to these books individually as they had collectively (DH, WH, IG). Allies will go away.
I'm guessing WitchHunters will get a PDF and White Dwarf treatment to completely undo allies in April or May.
