From their website:
Since the release of the second edition of its award-winning tabletop miniatures games WARMACHINE and HORDES, Privateer Press has seen explosive growth among its player communities worldwide. The excitement generated by our games has never been higher, and demand has quickly outpaced our production ability. In response, we have expanded our efforts to make our products as easily available as possible.
While Privateer has continued to supply new releases on time, fulfilling the high volume of back orders can require substantial wait times. In an attempt to produce and ship orders faster, over the last year we have more than doubled the size of our production staff, significantly expanded our manufacturing capabilities to include an all-new resin casting department, and converted more of our line to plastic. These efforts have significantly increased our production ability, and we are now shipping record-breaking amounts of product from our Bellevue facility.
