The Primaris Chapter Master Collection Set
Upcoming sets? This is quite the list of miniatures. This was apparently on the pre-order page for a brief time but is no longer in sight. Perhaps it was cancelled or pushed back due to the crushing demand for the Indomitus boxset?
While it was up it gave an error when clicked on.
Primaris Chapter Master collection, £452.
Apparently there were three other collections that appeared as well? I did not see them.
