They've stated that they want to take a few years off from the franchise to work on other things. I'm sure they'll come back to it, but it doesn't necessarily have to carry on with the timeline. They could go back to some other Avatar (they have 10,000 years worth of history built in) or they could jump forward or whatever. I just wouldn't expect anything out of this universe for awhile.So assuming the creators want to make another series after Korra ends and they either get the greenlight from Nick or the rumored Netflix pickup happens, then the next avatar would be coming from an Earthbending background? Fire before Aang --- Air (Aang) --- Water (Korra) --- Earth . Kind of neat that they could be thinking ahead with what looks like a super aggressive and fascist Earth kingdom in the previews.
$10 says that we'll continue to see bending in this series.$10 says Kuvira is the one controlling the bandits. Tell them to attack towns and then come by and "unite" the Earth kingdom.
You already have a thread for that, bro.$10 says I'm going to plow you.
