Ive been waiting for over five years for this since I first saw it being developed. As an avid NWN2 modder myself, and a hardcore Baldur's Gate fan, Ive ketpt a close watch on this over the years. However, it's not just one guy, there is a team of at least three doing all the scripting, although I think Drechner did most all the main area designing for the module.
I know what I'll be doing this weekend though when I get home! Finally, it's here.
