Yes, it's apparantly true. This autumn, TLK is being selectively released to theatres in 3D.
I couldn't care less about the 3D part, but the chance to see it again in theatres is something I've been dreaming of since I first saw it as a child.
There's an article by someone here with the official trailer for the release: http://www.cinemablend.com/new/Lion-Kin ... 24901.html
