I saw this over on dakka and they are saying this might be the 6th edition cover. I find it doubtful as there are only dark angels on the cover!
Does this mean that we will see hard cover 40K codexes?
Does this mean that DA is closer than everyone had thought?
Does this mean that I can finally dust off my robed marines and have a toga party?!?!
Only time will tell. Until then, enjoy your conjecturing!
