The original rumor that got us here
a regular of ours talked to GW asking if he could use Forgeworld in tournaments and he told us he was told that YES HE COULD, and that a FAQ for all of the Forgeworld stuff would be released by Games Workshop (not Forgeworld) giving all the pertinent rules to allow them in regular play.
This corroborates a LOT of rumors we are hearing about Forgeworld going mainstream from multiple sources. What we hear is that GW is waiting to set up a North American production center so that they will be equiped to meet the anticipated demand that will come with letting FW into regular play.
