It seems that we have a new pre-order up on Black Library Digital Editions; Warhammer Fantasy 8th Edition Rulebook. This is up for pre-orders now, with a release date of May, assuming that it will be on the 3rd.
So what does this mean for the possibilities of a new ruleset coming out this fall? Normally I would say it means its not happening, but in this climate its anyone's guess. Still I may be picking this one up.
Here is a link to the pre-orders.
