The Shield of Baal release is looking to be a let down for Blood Angels fans as it clearly doesn't further any physical release for the army or rumors of a two army box set, at least not yet. I love to hate Blood Angels but I like players very much and I sympathize with everyone wanting more for their favorite army. The Blood Angels rumors are the worst because they have all been dead wrong since before 7th edition dropped. When I see photos from a White Dwarf like we've seen from the latest Tyranids then I'll start believing some of the BA rumors.
Going into the Holiday season marks a busy time for GW, but on a stricter planned schedule. This can be seen with their LoTR releases especially for the Hobbit. It will be tougher for them to try and drop the Hobbit, plus Fantasy, and Necrons and Blood Angels in a short period. I think one of the 40k factions will see at least some release, but likely others will wait until New Years or later. Necrons seem to be just as imminent as any proposed Blood Angels release from all the chatter.
