"It may be set 70 years in the future.
Aang is featured in the series in the Spirit World, as Roku and past Avatars were to Aang in the Last Airbender.
Korra is from the Southern Water Tribe.
She has already mastered three of the four elements prior to the series, and is trying to master "Air". Aang's son, Tenzin, is supposed to teach it to her.
Most of the story revolves around a steampunk metropolis called Republic City. It's the epicenter of the world, and a virtual melting pot but is plagued by crime and a growing anti-bending revolution that threatens to rip the city apart."

The Only detail not confirmed is Aang in the Spirit world, but I'm certain he'll be apart of the series.

Yeah but given what we know from the original series. Aang would play similar role in the new series to Roku in original series.
