Depends, can 30k assault squads remove their jump-packs? In other news, new rumour pointing at Sisters of Battle being done and ready for shipping as well as Leman Russ (the primarch, not the infinitely cooler tank) being the next plastic model after Magnus. Amusingly, Jes Goodwin is an artist, not a rule writer. via anonymous sources on Faeit 212 Jes Goodwin has wrapped up the artwork and the rules for the codex. Sisters are ready and could be released within 3 months at any time The bad thing is that they have been in this state for more than a year and Jes has stopped the process. Also the next plastic primarch would be Leman Russ, but you probably know that already.
No, 30K Assault Squads can't remove their JPs. It's a different Squad type that fills that role, but those may be Legion specific. Interesting rumour on the Plastic Russ Primarch, as that is the forthcoming Primarch from FW. Could the source have confused an FW product for a Citadel one? If so, then maybe it's 40K rules for FW Primarchs in the next Edition of the Rulebook? Makes more sense. As for the Sororitas, they've been rumoured to be coming for a while now.
I took a look at the Musterbrand site, and it seems to be mainly themed clothing along with themed accessories. https://www.musterbrand.com/ For example, you can get a jacket with the main colours and symbol from a mainstream video game like Mass Effect, Mirror's Edge, or Halo, like a black jacket with red elastic on the bottom, a white bordered red vertical stripe up the back, and Mass Effect's N7 symbol on the chest. And then there's stuff like backpacks and messenger bags. Is it me or does this sound like some of the stuff you can find at Warhammer World?
GW just released a teaser for Deathwatch with a release date, 6th of August. Also in August a new paint and hobby range. Kharn might be taking a pleasure trip to Fenris this September as well.
