Except there was no "thinking" or "planned", it was definitive. This is the exact quote:
Sure, "with" could mean at the same time (the implied meaning) or in succession of and "that" doesn't have to mean the models' release itself but to the update in general. So, they could be delivering this in 8.3, and could even include a bigger event with the Gilneas hints we've seen. But to say it was communicated as anything but definitive is just blind, uninformed fanboyism at work. If you actually cared to be objective, you'd check before stating otherwise.Goblin and Worgen fans will be pleased to hear that the long-awaited model update for each will be arriving in a future content patch.
“Shortly after Rise of Azshara, you’ll see that,” Morgan explained. “These are the two races that haven’t been updated. They’ll have new heritage armor with that as well.”
I personally am fine with it being delayed (though upset if it was then shelved permanently). I'd rather have the new models get more attention with revisions and the patch be delivered faster. Unfortunately there's people that cling to anything negative from Blizzard as an excuse to either just blindly hate or defend.
