Roboute Guilliman is the next Primarch to appear in 40k, and will do so in March/April with a new plastic Calgar and honour guard set. This will be along side the next installment of the gathering storm which sees the Ultramarines, inquistion and Knights go to war with the Necrons (Revenge for, as the Guilliman sees it, his kidnapping by Trazyn) the Necrons combine their Might and go to war against the Primarch.

Mortarian will return later this year (look to Autumn time) with a release ala Thousand Sons.
