Looks like we have one more final week of the Fyreslayers to wrap them up. Next week's teaser image is "More Orange Beards and a Whole Lot of Chaos". Now don't get all excited that Chaos Marines may be coming, Lady Atia is saying not to get excited here.
So one more week of Fyreslayers, and then off to something 40k'ish?
You can see an image of the teaser here on Bols.
