+++ Wrath of Magnus +++
I try not to get excited by these things but Tzeentch just my feelings through the roof. This is going to be epic. Plus I noticed something as I looked through the video, it may be just dramatic licence but this Rubric has an assault cannon!
Update: This is of course now known to be a Soul Reaper Cannon, a weapon Thousand Sons squads can take if the have ten members.
