It appears the Queen albums are to be released in the Super Audio CD Format.

The Super Audio CD format promises better sound quality than regular CD. In fact - the same sound quality as the original master tapes. SACD's can't be played on regular CD players.

It appears to be a Japanese only limited release at this stage.
