Of course, I don't know this for sure, but I tend to believe that in his own mind, Asimov did finish the Foundation series. Anyone else wanting to take the ball and run with it certainly had a heck of a start to build on. Actually, I didn't know that another author(s) had done so. Can you name them, or the titles?
addendem: narf, Dune was written by Frank Herbert.
