I doubt we're getting anything before 1.5, that is either after summer or even christmas... It seems they are focusing on other things, like cross server queues, ranked wzs, expanding on legacy and creating new ops.
Tbh I don't mind the wait, if they reintroduce open world pvp I want it to be great, not just Ilum take 2.
It's a sad day for MMOs when people think WPvP equals developer controlled grindfest.
World PvP being centralized is not world PvP.
