Fan2Fan have provided scans of the latest Robot Master catalogue/comic, available with the release of Star Saver, Victory Leo, and the Victory Saber set. The scans can be viewed here, but please note that only the comic part is translated, the catalogue section is in Japanese.
Fan2Fan have also confirmed that there is a colour difference between the regular Star Saber and Victory Leo, and their counterparts in the Victory Saber set, albeit a very subtle difference.
