Apparently he is not working on it:
Will we ever see Obsidian return to its Planescape roots, as we are seeing with Bioware and Dragon Age?
Probably not, I don’t even know who has the Planescape license now, and I’m afraid if I went back to it, I’d fuck up a good thing. Then again, we’re going full circle on Fallout now and that’s going well, but I’m not working on that project (it’s in the very capable hands of Mr. J.E. Sawyer), so that probably explains why it’s going well.
