"For PvE players, we’re adding more content and new types of content to the game so people have both a larger range of stuff to do in existing locations, as well as new places to explore and new features to see to give them even more to do. Some of this content we’ll be sharing ahead of time, but other parts we will leave for you players to discover. We also want to better reward players for doing a number of the things in the game that currently aren’t rewarding enough, and add new features and things to do that expand the range of content a player can experience.
For folks interested in any and all of the above, we’re also adding world events, festivals, new rewards, and greater over-all depth to the game to build towards offering the richest experience we possibly can. We realize that when you release an MMO, you need to very early on show a commitment to your customers that you’re going to support the heck out of your game. The fruits of these labors will be appearing in GW2 VERY soon, and you’ll start seeing new additions come in rapid succession as we continue supporting our live game."
