Both of these new miniatures, the Primaris Captain and the Primaris Librarian, come with alternate head choices, but the Captain in particular also comes with multiple weapon and hand options - the first real versatility we have seen in the Primaris range so far. Some of the armour on the Librarian is interesting too, with a new helmet, backpack and arm bracers. Neither of these models are cheap - keep that in mind before opening you wallet!
Meanwhile White Dwarf is out next week. We had a bit of a spray about WD a few weeks back, so here's hoping it's an improvement on recent issues.
The Tau get a look in next week with the Farsight novel which looks like more of the origin story, so that should be cool!
