I'll throw this out there too...
There's some chatter that you could hear a beeping sound on the final shot of Cad Bane laying on the ground. This could be a beacon sound that his droid & starship were en route to rescue him. So perhaps he's not dead after all? While I like the thought, this probably is wishful thinking.
Instead I'm willing to bet that we'll see a Cad Bane spinoff series within 3 years, because the main thing people will remember about this series is the live-action debut of Cad Bane, and the impressive deepfake tech of Luke. Fans will be dressing up at conventions, clamoring over time, wanting more of Cad Bane. We've never seen a Star wars character totally command his limited screen time since....well, Boba Fett.
And why not finally do the featured dark scum & villainy series that the fans really want? Just make it an underworld prequel show (or even a standalone movie) featuring Cad Bane & his cast of Bounty Hunter rivals & fan favorites.
What I'd REALLY love to see is the tale of Boba delivering Han Solo in carbonite from Cloud City to Jabba's Palace. How all great Bounty Hunters were on his ass trying to collect the greatest bounty in history. Cad Bane, Dengar, Bossk, IG-88 etc etc all on a chase through the Outer Rim & underworld, outmaneuvering one another to nab Jabba's biggest bounty. You could even cast a thin actor to play Boba with a Morrison voiceover to match the period. Helmet stays ON, Boba cold-blooded, disintegrating, etc etc. Fix the wrongs of the Book of Boba. No Jedi, no kiddie shit, straight up scum badassery.
Now that's a show IMO.
