But are there any plans to have limited PvP/PvE zones in Guild Wars?

I haven't been inside the fissure of woe yet, so forgive me if this zone is exactly that.
DAoC was the first to offer this, and it has had excellent results; part of what makes an area like this so challenging is knowing that at any time your adventure can become incredibly perilous, if not downright deadly...
it's all about the antici . . . . . . . . . . . . . . . pation!
