They aren't official dates, no one official said that. It's just a rumor that's been spreading around on tumblr. Honestly I don't think those dates make any sense, because we're supposed to be shaping the experience and the day 7 people can't do that with only a week. Also there was a phone conversation released where it said that no one will be getting they're emails for like a few weeks. So no I don' think those days are right....
