User blog comment:WhiteStorm82/SAO should have a whole new season/series/@comment-4270236-20131231151616

Well, I see that you're a new fan of Sword Art Online, and haven't fully read anything. But that's why I'm here, to let you know.

Sword Art Online is based off of a Light Novel series written by Reki and is still being rewritten and published even now.

And the response you're looking for is that they are clearing each floor of Aincrad, however, it's more of a side story. And for starting new adventures, Kirito does venture to two other new VRMMOs named Gun Gale Online(GGO) and Underworld(UW) and meets new friends(most of them are girls).

Are they making a new season? Maybe, maybe not. Not sure if anything new revealed yet.
