There are lots of images starting to leak about showing off a couple codex/army book pages and more images of the new models.
Here are some pics. Note that they will probably not be up all that long. Take a look, as there are a lot of interesting things going on in this set. Daemonic Instability is mentioned. I did not see Feel No Pain. There are some random powers as well as some talk about Daemonic Gifts.
Please note there are only little bits of information available. I am sure that when the magazine hits the stores on Saturday, everyone will get a better chance to view these pages in a better context. This is just a snippet of things to come.
