I'm with Cheese here, GH is crowded with half-dead forums so I'd suggest some "cleaning" first and we'll see how GW2 thread grows when the game releases.

Previously I did suggest on making dev specific sub-forums like this:


How about a new forum called MMORPG or Online Gaming instead of nesting inside Gamers' Hideout?

Perhaps it's a bit too big to dream eh? 
Just think about the clicks and custom ad forum that you can get from GH.
