If I had to guess, I'd imagine waypoint flags similar to heros. We'll see.

As for the updates, I'm mostly indifferent. Sorry for anybody who liked to play a paragon. I'm still waiting some sort of decent in-game auction system (No, the trade tab on the party search isn't good enough). Removal of PvP players restricting PvE areas would be nice too. I don't bloody care about Europe winning, let me go to the places I want to when I want to! I doubt I'll ever see either of these though, so GW is going on the back-burner for a while.
