Well... like it or not, but if you have watched all the Live Letters, there are Sets which are most likely an "upgrade" from current Relic/Myth Gear including new Weapons. There was not a word of how those would be obtainable, but who knows.. maybe the Relic Sets will be upgradeable as well at one point. Personally i would not mind that.

Probably not in the near Future.. more like after Levelcap goes up;
