As the title says first of all here is the link to see the newest Korra Nation clip, someone uploaded it region free so everyone can view it, it is Korra, Mako, Naga and Pabu vs some equalists.
Also here is a link to view Sifu Kisu’s interview for Kung Fu Magazine

Not a whole lot in terms of reveals, but it is quite indepth on the martial arts styles of both ATLA and Korra, well worth a read.
