Got my mits on the new Codex now and delighted with it. Loving the variety, loving the exotic wargear and loving the many ideas of models and units I could now build.
One of my favourite bits is the idea of the brotherhood champion. Last year I converted a the below model. I've been playing him as a tooled up Inquisitor but in the brotherhood champion he's found his true identity.
For those interested this is an Emperors Champion model with the back pack and cloak from Gabriel Seth.
