The Destiny Letters
Ex-Bungie Community Guy Matt Soell, who was with the company during the early Halo days, has penned a response to some of the complaints about Destiny's reveal being more "hype" than "substance". It's well worth a read, so please go take a look (Warning: little bit of NSFW language. No images, but some imagery.)
If you ask me, though, the crux of the issue is right here:
For years now, even before Destiny was a rumor, people have been calling for more transparency and less hype from Bungie. If a few pieces of concept art and a YouTube video are "hype," it's only because Bungie's process has made less feel like more. They do not deluge the press or their fans in an antiseptic wash of tedious data. Anyone can do that. Bungie wants your entry into this world to be an experience unto itself.
Soell makes a good point; the Destiny reveal was not a planned press event watered down; it was an extension of the Cortana Letters-type experience to the mainstream gaming press. Looks like not all of them had as much fun as some of the fans (myself included) did.
