I've written a little article about the latest limited triple lp edition of "Return Of The Champions": http://www.queencollector.net/rotc.htm
The box is really great and it's a pity that this kind of box hasn't been released for a pure Queen (or 100% Queen) edition like they could do for the "On Fire" edition in triple lp.
The vinyls aren't just contained in a gatefold sleeve. This time they are inserted into a real carton box wich is bigger and better than any previous edition.
All the best,
