After watching the video's of Guild Wars 2, it looks a lot like what DAoC 2 could have been with the world pvp. They have keeps and towers! You can check out the videos here: http://pc.ign.com/articles/121/1219178p1.html
just checked it out, and that looks great! you can definitely see that they are taking a lot from DAoC in their world PvP. He mentioned 3 faction combat (yes!) and the keeps brought back some fond memories
FYI - Beta signups are here: https://beta.guildwars2.com/
I read an article that it'll only be open for 48 hours though
I missed the beta sign up! Hopefully they will add another one soon. I would love to try it out!
