We may assume Episode V (& VI-VII-VIII-IX) is off the table now. Very unfortunate, this movie format was a very good idea to extend the “movie saga experience” with TCW material and so far the 4 episodes were a vast improvement over the episodes.
I wouldn’t count him out yet, life catches up with everybody.
That being said. The actual TV series after Episode IV of this movie series is actual really good, after you finish A Galaxy Devided you could just binge the rest of the series and be fine. I hope he continues the movies, but he’s smoothed out the worst parts already.
