Well, there's two members that we will all miss.
Nah, GW2 looks good as well, although it's another MMORPG, I'm burned out on them now, can't play another one of those for a while.
Isn't just an MMO though. Guild Wars wasn't, neither will this be. It'll totally, without a doubt, blow any and every 'MMO' out of the water. No boring 'go kill 10 skeletons' type quests , and you feel like your actions really do impact the world. It's insane they don't ask for a subscrip fee.
I'm on the fence about D3 for now, purely because I don't want to spend a lot of cash on a game that I'll ditch once GW2 is out.
