Quotes from Colin Johanson:
"We’re going to do a release on the 20th that is intended to be our big anniversary release celebration," he explained. "That release is intended not only to provide a lot of awesome content for people to experience, but to also set the tone for what they should expect for the living world and the types of things we want to do with events in the year to come.
"It takes the story of the last year and brings it all together. It makes it clear where everything has been going and really closes a lot of open questions that players have had. It’s a story that really affects the entire world and permanently creates content and change for the entire world game-wide, which is really something that’s important to us and we want to showcase that that’s where stuff is headed.
"I think we have some really ambitious plans for next year for what we want to do with the event system, and this kind of showcases a little step of where that can go."

"We will offer a gift to players; it’s something we did in Guild Wars 1 and we’ll bring it back in Guild Wars 2 when their character turns one year-old," Johanson revealed. "There’ll be a gift that becomes available, so that’s something for them to look forward to, and we’ll compliment this with a lot of other exciting stuff as well."
