While this would sell from WL like hot cakes, I cannot fathom them doing this. Ultimate Magic was delayed and issued in two parts. Ultimate Combat officially comes out in two days. Those of us that get early copies have only had it for 2-3 weeks. So for WL to have Ultimate Combat, Field Guide to PFS and the other guides - Faiths, Revisited and any others that were just released - usable in HL in a timely manner seems too much to ask. Remember, WL isn't just doing HL for Pathfinder. They have Shadowrun they were discussing, M&M 2 and 3, 4e, and so many others that they need to focus on - in addition to updating Herolab itself.
Although, it would be totally Kick Ass if they did announce it at GenCon.
