What GC meant was that you need to pace the consumption of content or the players will eat it all up in mere weeks after its release, which will not last in the long run if you want any meaningful content. As much as I dislike TBC, one of its strengths was that a lot of the content did not become obsolete during the course of the expansion. MoP has taken this to heart when designing the content while not making the same mistakes done in TBC.
Besides, how the heck does your interpretation make any lick of sense when looking at patch 5.1 and 5.2? As well as promises of even faster releases of patches of similar calliber as the ones we know about thus far?
