I'm sure I'm one of the three probably.  I do like to discuss game design.  So when a new edition comes out of ANYTHING not just D&D, I find it interesting to discuss the pros and cons of various design decisions.  I'm definitely not trying to keep anyone from playing 5e or any edition of D&D.  If I was, I failed miserably for 5e which seems to have been very successful. 
A lot of game design discussion usually flourishes during the release of a new edition.  Do I hold out hope that WOTC will ever come back my way?  My brain says no but my heart always hopes.  My brain though is a lot smarter than my heart.
