Well first of all, there's no evidence that there will be new jobs at 2.0 launch. I mean it's possible, but there's no reason to assume there will be.

Secondly, I think it's pretty safe to say that the end of the end of the relic weapon quest will be coming sooner rather than later. The weapons are great, but they're not game-breakingly godly and using FFXI's relics as a reference isn't useful as they're two entirely different beasts.
