Previously, Restoration said remaking/restoring Heroquest was just too elusive. A joint venture between MB and GW was a product of its time. Further, at least one other publisher (Chaosium?) has a TM on the name Heroquest.
I guess money talks? I don't know how it's happening, but there seems to be traction.
Personally, if this materializes - I think it's in great hands. Rob Daviau, Justin Jacobson, and Mike Gray will make this thing shine.
