I am clearly far too late to answer here, but i will emphasize one point. Im guessing your question was brought on by the new patch. These content updates have always been free, so starting in about a day all the players currently able to will be finding new dungeons to explore, trials to overcome, and raids to conquer that werent available yesterday(along with a host of other new options and features). These types of content update patches seem to happen every few months. The devs are also planning/working on the next expansion for the game. Expansions arent free, are optional, and include a lot more content all at once rather then doled out a little at a time. So far they havent released many(any?) concrete details on the next expansion, and most of the people i talk to are guessing we wont see it until probly next summer.
