?!?!?! It was a JOKE!! YES, they have the rights to do Mystara, but he specifically said that KenzerCo has NO PLANS to bring back the campaign setting! They're pretty much only using the OD&D modules and converting them to HackMaster, which is what they're doing ALREADY, and have pretty much said they're doing since DAY ONE!
Where people got the idea that KenzerCo was revisiting the Mystarta setting is beyond me... The Garweez Wurld is big enough to encompass ALL of the 0E, 1E, and 2E campaign settings... so it won't be Mystara even IF they use more than modules.
Take a deep breath, everyone, read carefully, and enjoy KenzerCo's wonderful products for what they are, not what they joke about....
Sorry about that,
Chris
