Are we really going to do this?
Isn't it pretty damn obvious that the previous development method at Blizzard had them fiddling with plans and designs for ages and ages - and then spending a year and a half building shit.
Now they push out stuff continuously - but it's pretty obvious no one over there has much time to think about the overarching stuff anymore. They pop random features into the dev queues and push it. This announcement was a good example - they had to go "oh shit, can someone gimme a list of the features we're building, I have to make up a story line for this expac reveal we have tomorrow?"
I'm not going to argue the merits of "pure agile development". I'm saying Blizzard can't handle this shit.
