The readers here are just awesome for keeping their eyes and ears open. Here is a bit that gives a little insight that 1; Blood Angels up is coming, and 2; formations with assaults from deepstrike (nasty).
Please remember that this is a rumor. Managers are supposedly getting more information nowadays, but still give this the normal "rumor" status.

I am actually really interested in the new Blood Angel Campaign. I was at my the GW store in my area and had a chat with the manager there. He said he knew a Blood Angel update was coming and he was super excited for it. He said it featured formations with "assaults from deepstrike everywhere."
