I get the feeling they're stepping back to reconsider rapid hotfixes after the backlash from the mythoclast nerf and the planned atheon 'fix', as well as the tepid reception to both wrath and ib.
They also mentioned vaguely that the first big patch is/was in cert, so that may be coming soon, which also might have affected event plans.
This is all wild speculation based on a handful of nuggets gleaned from spare sentences of useful info extracted from interviews between paragraphs of storytime written by Deej.
I think you're right. As much as I'd like to think they know what to do next, IB and Wrath both showed that Bungie was too tepid with the fanbase that's actually going to keep playing this game.
I know they're a company known for shooters, but Bungie needs to realize the audience for Destiny and the audience for Halo are different. The people that will continue to play Destiny want high-tier events and new gear, not just maps and more crappy Dinklebot non-story. The people that play Halo want maps and gametypes.
They're learning, but it seems like its fairly slowly. Iron Banner and Queen's Wrath were just too aligned toward keeping everybody happy, when really only the hardcore players cared about the events.
