I play video games with a friend of mine at 10 o'clock + every week night. We've played TF2/Rift/Civ5/a series of Risk browser games/BF3/EQ/EQ2/anything and everything in between. We've come to the conclusion that nothing is fun anymore. Our last hope is this game given its quest system, WvW system, and combat system. I'm holding my breath until its release; hoping that it's all and more that they are promising. With these expectations I know I will be disappointed with something along the way, but what I do know; and find it relieving, is that this game will be much different from its predecessors.
Rift was refreshing because of the dynamic events, and the continuous fights between the factions during those events. Warhammer was the only MMO I enjoyed consistently queueing for pvp. Even the weekly fight for Wintergrasp was entertaining in WoW.But, like everything else in these games it quickly grew to be a monotonous experience. DAoC was the only game that held my attention in the RvR experience. I'm glad to see GW2 emulate it and hopefully mature that experience.
Fair warning with the beta signup: according to GW2 they've had an overwhelming amount of signups, and it looks like the chances of getting in are 1-100. From what I've read, they are going to add more slots to the beta events given the interest, but have yet to find anything from arenanet to confirm it.
Also, if you missed it here is a AMA(ask me anything) on reddit about WvW-

If the answer below is how they want WvW, I'm sold.
