I have a strong feeling that what will make WotC decide a new edition is in order is not a bunch of threads predicting doom or change, but rather slumping sales on their D&D line, and a sagging user base. Those are the times you need an infusion of new blood, and the energy that a new edition gives. However, they already know full well that too often a release alienates diehard fans, which you need a certain percentage of to do your grassroots proselytizing for you.
