With no codex release yet, there has been a lot of talk about what the Blood Angels codex week will look like. According to the latest, there will be a reboxing of Space Marine Tacticals, and this rumor set takes it a bit further about what may be coming.
Please remember that these are rumors.

from what I understand all the existing BA specific boxes are also getting updated to the new style: (SG, DC, Baal, Dread). Though, I do believe sources saying BAs are getting a new Terminator box.
I believe BA have 1 vehicle and another "marine" box in this release. but its a very small release, 3 kits total...4 if you count the "campaign" box with the captain. And they are saying no Mephiston LOW, that that's just internet wish-listing run rampant. (Which, I had fallen victim to myself...too many voices)
take it for what its worth, though, cause none of my sources had the tyranid release.
