What I would love to see would be an expansion per year, plus a patch every 3 months. Considering the supposed size of the WoW team, this does not seem unreasonable, and to be honest, I feel it is should be a given.
Hey look guys, it's a person who has NEVER MADE A GAME IN THE HISTORY OF HIS LIFE TELLING OTHERS THAT THEY SHOULD BE ABLE TO DO NEW EXPANSIONS YEARLY!
Go armchair dev something else, like an indie game. Not a AAA MMO.
