For now we have got alot of bug fixes, glitch fixes and some content changed but we have to wait a few weeks/months before we get new content through Game Updates. I expect more zones on the continent of Tyria as we only have 1/3 or 1/4 of tyria playable. I read on the mmorpg.com forums and reminded me of the great wall that the Tengu guards and also the Fire Isles from GW1.
These Game Updates could have huge events before you gain access to the new zones. Maybe a full scale war that goes on for a few hours? when the war is over, you gain access to the new zone. kind of how CoF works with the event going on denying access to anyone.
What do you expect from Game Updates?
