It seems that there are quite a few pesimists out there. You guys are making it seem as if Interplay is jealously hoarding the FO liscence, and that to buy it would cost an arm, a leg, and a pint of virgin blood. Look at this article that came out a couple months ago on gamespot.com

Notice that Herve Caen, Interplay's CEO states that Interplay will probably try and have an outside company work on it. Because several of the origional developers are working for Obsidian now, it would not surprise me if they were one of Interplays top choices.
