Legend of Korra
No idea how many people here have known about it, but apparently Platinum Games (Vanquish, Bayonetta, MG: Revengeance) are making a Legend of Korra game for the major consoles.
It's gonna be downloadable. I read somewhere that it takes place between Book 2 & 3. Korra's design is her Book 2 design, so I guess that makes sense, although she's shown fighting Equalist Chi Blockers and Sato's Book 1 Mech Tanks.
~ I was rewatching Book 1, and I realized that Republic City would probably be a good setting for an 'open world' Korra game. But meh, just my musing.
