Privateer's Editor-In-Chief Joe Martin posted this on their mailing list in response to a question about the Lock & Load series of supplements:
"L&L is a line of books planned as "crunchy bits" for lack of a better term. Our dedication foremost is to the IKCG and WARMACHINE, but after that we have an ambitious plan for 2003. Beyond area books, for example, a Corvis Citybook, and some adventure mods in the works, we have a couple of L&Ls on the docket. Everything's very tentative right now, obviously, until we get the IKCG and the WARMACHINE Rulebook out, but we do plan more Lock & Loads. As the schedule becomes more concrete, we'll let everyone know the plan. Hope that kinda-sorta answers your question."
He also mentioned that the Iron Kingdoms: Campaign Guide is planned -- but apparently not definitely set -- for April.
