Games Workshop posts up a new teaser for Warhammer 40k. We will find out what it is on 6-23-12.
From their post:
+++Transmission intercepted, advanced encryption override initiated+++
Servitor 13 has just intercepted this video link. At present we have no firm details as to what it is about, but it appears to be related to Warhammer 40,000. Since intercepting this transmission, communication with the Studio has fallen suspiciously silent. Servo-skulls have been sent in to investigate – we will let you know of any future developments.
