Well I couldn't help myself, I need to speculate because well I'm at work and extremely bored. So I'm thinking, "What's next? What will they be adding to this game?" And than I'm thinking, "Well let's make some guess's because guessing is fun."
So anyhow I was thinking about things like further class specifications, like a paladin classing into say a Champion, or a Fallen Paladin (this would probably allow another city betrayal quest, but by becoming a fallen paladin instead of like betraying at lvl 15.) Or maybe a templar classing into an Avatar (of whatever particular god), or Blasphemer (for causing some terrible action against their god.
Anyhow, I just thought it'd be fun to start an Idea thread for the heck of it.
