Okay we have an official super clear comparison between all the versions of this re-release, including a comparison with what will be in the 1.10 Patch for last-gen owners.

The chart is in Japanese, so I'll translate the column on the left indicating the features. The rest should be self-explanatory.
New Features:
- New characters and events (Included in all versions of SoFS, will be added in the 1.10 Patch for existing users)
- Story and world additions (Included in all versions of SoFS, will be added in the 1.10 Patch for existing users)
- Graphics and performance upgrades (Only included in next-gen versions of SoFS)
- Improved online multiplayer (Only included in next-gen versions of SoFS)
- Enemy and game design adjustments (Only included in next-gen versions of SoFS)
- Various balancing tweaks (Included in all versions of SoFS, will be added in the 1.10 Patch for existing users)
Not adding enemy and game design adjustments? uh. Maybe it's just stuff tailored toward 6 players.
