Hopefully soon. I've been playing a lot of Guild Wars lately, and been enjoying it quite a bit. The best information on GW2 seems to be here (http://wiki.guildwars2.com/wiki/Main_Page). In particular I find the event system (http://wiki.guildwars2.com/wiki/Event_system) as described as having a fair bit of potential. It certainly could eliminate a lot of the sameness of most quest systems, something that the missions in the first GW also did.
It sure does sound interesting but I don't want to get too much excited about it. It is years away.
