Thats right, the next campaign is now being rumored to be round two of the Crimson Slaughter vs Dark Angels. This would be interesting as it might give us some updates to two codices that many people want to see updates for.
Please remember that these are rumors. The last rumors we had of a new campaign placed it towards the end of April or beginning of May. There is a lot of room for more information to come in.

I have a bit of info in regards to the new campaign set.
While the date is currently unknown the forces within are crimson slaughter and dark angels. The idea behind the set is that you buy the Dark vengeance expansions plus the dark vengeance starter kit plus the campaign box and end up with all the required models to run any of the formations in the books.
No real idea on the contents as of yet asides from the chaos character being a sorcerer and the da having either a da specific tactical squad or 10 company vets. My source wasn't too clear to tell you the truth. Oh the dark vengeance story missions will also be a part of the campaign and reworked a bit to be used in regular games.
