They released this information just this past weekend. It was exclusive content for folks who attended the event. I'm guessing that SE will give folks who paid money about a week to revel in it while others have to get by on gossip and hearsay before they add it to the official site.

It's all incentive to get people to pay money the next time! "Man, if ONLY I'd ponied up the cizzash, I could be talking about this on the forums, too, instead of begging for scraps of info from the people who did!" SE wants it to be worthwhile to pay the money, after all - otherwise, why pay it?
