IMHO, the outlook for a Kenobi film hinges on the outcome of ep 8 & 9; and the lineage of Ray.
Personally, I think between the first 3 episodes and the clone wars series, we had plenty of Kenobi.
Give me more Mace Windu, Ahsoka Tano, Maz Kanata. How about a whole movie about Darth Vader hunting down Jedi under "Order 66"? We only got a small taste in Rouge one how "bad ass" Vader was. Adm. Thrawn seems to be making a comeback! I love the darker side and hope we get more backstory on Snoke too. The future is bright....we look to be getting new starwars films at a pace of once a year! What a great time!
