Guild Wars 2 -- the September feature pack -- isn't far behind. The pack aims to improve several parts of the game, starting by demolishing the concept of dungeon owners. Currently, the first player to zone into a dungeon is counted as the "owner" of the dungeon, which can lead to problems if that player disconnects; by contrast, after September there will be no dungeon owner, avoiding issues with progression if that owner leaves or gets kicked.
The game's crafting UI is also receiving an overhaul, making it faster and easier to access crafting sub-components without navigating away from the main item that you want to craft. The update will also bring a number of performance improvements to make the game run faster and better on various bits of hardware. Take a look at the full update for a few more details as the feature pack release approaches.
