GW series is historically mostly about pvp, and the pve content is mostly just a side game. There's no indication that this will not be the case in GW2. Small scale coop pve only, for example.
They can certainly beef it up, but it's largely a pvp game.
The problem with GW2's PvP is the adding of mechanics that doesn't jive well with the game they want to make, namely the whole dodge mechanic. That seems to be more suited for a pattern based action game than a game where 2 or 3 other guys are bashing their skills to kill you. This whole marriage between action and MMO is going to end on a divorce.
I think it flows perfectly. Playing my warrior it can be quite helpful against spellcasters.
