If this is true it's HUGE for 40k. Having a continuation of the 40k story is just incredible. I can't remember the last time the "current time" that you effectively play the games in was updated this much.
I'm definitely excited about 6th edition now and am going to start saving for the collectors edition which (if going by Warhammer Fantasy) should be pretty impressive!
