After nearly two years(!) of signature gathering, we submitted the petition  a couple weeks ago.

And whether by effort or coincidence, you can see the news announcement here!:

A million thanks to Shawn Stanley, Webmaster of the Vaults of Pandius for steadily bringing this to reality! And also to the 935 of you who signed our petition. And above all to Jeff Grubb, a gentleman among game designers, who's offered to write a new foreword for the worldbook!

In deep gratitude,
-Shane Travis Henry

Peace out. See you along the Mystara Way...
