EA_Jesse snuck in with an edit to his original post he made earlier with the Teaser Trailer. Here is the updated notes:
Over the next few weeks we’ll be sharing more information on our next major update which will launch towards the end of this month. This is our biggest update yet that includes Guilds, Raids, Guild Chat and more. Raids will introduce new rewards you can’t get anywhere else, including new pieces of gear. We can't wait to get it into your hands and hear what you think!
