Yes I have been living under a rock for the last day, but these appeared in my inbox this morning coming from somewhere on Facebook originally.
Then there is now an image as well that has the Primaris Apothecary and Chaplain in it.
Not 100%, but Ive been told these originated from here
Then there is this, which shows a Chaplain and Apothecary in the middle left!
Update: Did you see the size of those plasma guns along the right hand side?
