Hello Avatar Fans, it is Airspeed Prime here to give you some very important information regarding the release date of Avatar: Legend Of Korra.
Nick have finally started a Korra forums section on their own messageboards http://www.nick.com/mynick/messageboards/viewboard.jhtml?bID=106921
So here is the screenshot of the Boards info
So this is a very good sign and finally a mention of the date from Nick themselves. That said this is not confirmation of Spring as we do not know if the people who run the boards have all the information.
So hopefully unlike David Faustino’s twitter date this one turns out to be true.
