It's going to be harder and harder to meet the demands of all the players. It already is.
from what i learn in marketing is that you will never able to satisfy a consumer especially videogames customer. The way i see it, people this day demand too much, i though the content they going to give for upcoming expansion is already good enough. with the exception of male viera and stuff, but that's different take.

people just love to shout nonsense stuff especially in internet because you know... its internet. if anything developer should not do 100% what consumer want, hear them yes but only as input/suggestion.

off topic but look at swtor expansion announcement, nothing happen, the fans happy, casual ok with it, general people is the usual "the game still alive?" comment. people flock to the "hot news" and that including those troller, "adding fire to fuel" kind of poster.
