Sounds like some nice stuff for the sPvP crowd, not really my cup of tea, its WvW which interests me. Hopefully that will get some additional features down the road too (such as guilds who claim towers/keeps being able to build a waypoint at their tower/keep for guildmember use, and a repair npc, in guild notification if a keep/tower you have claimed comes under attack so that you can head to defend it, some kind of ability to donate supply to a keep/tower which you are carrying, some kind of way to dismantle siege weaponry that you have built and get back either a portion of the supply, or have a portion of the supply donated to the nearest keep/tower, large shared WvW dungeon and so on and so on)
