If we combine Adigitalman’s Battle of Coruscant from his Clone Wars edit and Madman’s Knowledge’s ROTS Extended Edition (ROTS + Siege of Mandalore), we would get an ultimate edition.
Adigitalman (2D Clone Wars) + Bobson Dugnett (Deleted Scenes) + Madman’s Knowledge (Siege of Mandalore) = An ultimate edition.
Check out the work of /u/NumeralJoker on reddit. Back in May he made a 4hr30min edit of Revenge of the Sith. Has all the good deleted scenes, plus the entire Siege of Mandalore, plus the Battle of Coruscant from the 2D show. All edited perfectly and available in 1080p/4K. He’s also done 1080p/4K extended edits of TPM, AotC and Solo.
