Okay, I just noticed on the news section of Stephen King's Dark tower site (Apologies if this has been mentioned elsewhere):
Discordia Chapter II in Development
Posted on: 9.22.10
The much anticipated second chapter of Discordia is currently in development and is scheduled for release in Q2 of 2011. Robin Furth and the team that produced the original browser-based adventure return with an explosive sequel that will both shock and awe the constant reader. Be prepared for anything... "and drop anything that moves."
