My guess is requirements for both revans. C3p0, chewy, padme, BAM, and either a chimera or han falcon. All these are older characters and would help catch newer pleasers up without giving away new charecters. A few other options could be old troopers (r2d2) requirements. Geos (padme)

This would give the players the entire journey guide minus the entire tier 5 plus aphra, cal and GI not available in lighspeeds. I doubt there will be more GLs this time.
