Great list, sounds like the most accurate one yet. Don't forget that concept art has given us some confirmed production numbers as well. These are my best guesses. Bounty Hunter Arc 5.23-26 (confirmed, probably finale for s6) Crystal Crisis 6.01-04 (confirmed, s7 arc) Echo Arc 6.05-08 (probably, s7 opener) Wookie Arc 6.09-12 (probably, s7 arc) Dark Disciple Arc 6.13-16 (confirmed, s7 arc) Pyke Arc 6.17-20 (very speculative, methinks an s8 arc?) Son of Dathomir 6.20-24 (confirmed, s7 finale? S7 needs a maul arc, so this shouldn't be s8 material) Rex/R2 Arc 6.25-26 (probably, end of s6 production batch, could be an s7 arc or even finale) Padme Arc 7.01-04 (very speculative, likely s8) Unknown Arc 7.05-08 Ventress S8 Arc 7.09-12 (very speculative, but definitely s8) Return to Mon Cala Arc 7.13-16 (very speculative, definitely s8 though, late s8 my guess) Maul/Ashoka/Bo-Katan S8 Arc 7.17-20 (confirmed to exist, likely pre-finale, s8) Finale 7.21-23 (The finale of course, s8) That means Season 6 gets 21 episodes, season 7 gets 22, season 8 gets 23. A definite estimate, but not an unreasonable assumption either.
