Pre-orders are now up for Codex: Imperial Knights. Its sitting at $41 USD as rumored, along side the Imperial Knight Companion for $74.25 and the Limited Edition codex at $115. There looks to be some cool artwork in the limited edition and can't wait to see the cover of the codex a little larger.
There are also some new novels being released, like the Knights of the Imperium and Path of the Archon. I find it odd that these Black Library releases are being posted up on the main GW pre-order page.
