At first glance the release page for the Queen's Speech patch made the patch seem like it may be a bit boring. But since the original page was released there have been a few hints from Anet that this update may actually be fairly exciting as far as living story content goes.
For anyone who hasn't seen the "hints":
first a blogger from GW2 Guru was sent the following from Anet
http://www.guildwars2guru.com/news/1220-watch-out-for-scarlet-on-august-20th/
and recently the release page for the Queen's Speech has been "vandalized"
https://www.guildwars2.com/en/the-game/releases/august-20-2013/
Seems like the next update may turn out to be pretty interesting story-wise
*Edit: for anyone confused by the reference to "Scarlet" from the first link, she was mentioned as someone who was higher up than Mai Trin (the Aetherblade Dungeon boss) among the Aetherblades, and is potentially their leader.
