Even though Cobra Kai Season 6 has already been officially released as one complete season on DVD on March 3, 2026, and will likely receive a 4K Ultra HD release at some point along with the rest of the series, the creators will still need to produce a revised extended version—or, in other words, an Extended Edition of the entire final season. This version should serve as the main premium release of the Complete Series 4K Collection later this year in 2026, releasing as a standalone 4K set and on Netflix simultaneously to ensure a unified experience for the entire fanbase. Sony and Netflix should use the production of the 4K Master as the opportunity to move beyond the standard versions and deliver this updated Extended Edition, providing the production team with the necessary window to complete the high-quality restoration and manufacturing required for a definitive premium set.

When they produce this version and release it on 4K, they will need to go back and make some changes to all 15 episodes such as adding deleted scenes and alternate endings, cutting out or modifying certain scenes, using green screen and chroma keying to insert characters into existing footage, bringing back more characters that they couldn't include in the original version, reshooting some scenes, or even filming entirely new scenes that fit with the existing ones for this updated version. And when I suggest filming entirely new scenes, I am referring to filming scenes on a smaller scale rather than a full scale production. If getting the entire cast and crew back to film the new scenes is impossible, they can just work with one or a few cast members at a time and work around their schedules in order to make it feasible.

They need to do all this because they just rushed through the entire season splitting it into 3 parts and didn't give enough time to explain everything like they should have. It felt like they were just trying to tie up all the loose ends without any real thought or depth. The writing was bad, the pacing was off, and some plot points were wrapped up way too quickly while others were just completely forced. I honestly think they ran out of time or ideas and had to rush to the finish line. Plus they just spent too much time on the Sekai Taikai instead of exploring more storylines that needed to be wrapped up and in doing so left so many untold and unresolved when it was supposed to finish everything. They also just spent too much time on the main characters instead of also focusing more on characters they hadn't shown much of. An extended edition could really help wrap things up better with more scenes, more character development, and hopefully, more logical resolutions.

So yeah, they're gonna need to go back and re-edit the episodes and fix a lot of mistakes that they made and then make the extended edition the definitive version of Season 6, and Netflix will also need to replace the original streaming version with the extended version on their platform on the same day it releases on 4K. And also when the extended edition releases as a complete season on 4K, each disc should be labeled with the individual episode titles they contain like the previous seasons did instead of them being designated as Part 1, Part 2, and Part 3. They will also need to release a trailer and a poster for the entire season as well given how Season 6 is supposed to be a complete season and the previous seasons have had full season trailers and posters. 

Finally, as a Complete Series 4K Collection should be released alongside the standalone Season 6 4K set, Sony and Netflix should use the development of the 4K Master as the opportunity to produce remastered extended editions of Seasons 1–5 as well. For Seasons 4 and 5, the creators should film new scenes on a smaller scale—similar to the plan for Season 6—to resolve lingering plot points, while also implementing visual effects to enhance the Sekai Taikai setting and other key environments. Seasons 1–3 should be updated with restored deleted scenes and movie-quality visual effects, such as the digital restoration of the original 1984 Mr. Miyagi house architecture but have it slightly modified for all 6 seasons. They should then replace the original versions with these updated extended versions on Netflix and make them the definitive versions as well.

I just thought that they could do all this since Season 6 hasn't been released on 4K nor has there been a 4K release of the Complete Series yet. Sony and Netflix will also need to provide the budget for the creators to do all of this and support them with producing and releasing the extended version of Season 6 as the primary focus, while also making these updates to the previous seasons as well to ensure the entire series is preserved in its ultimate 4K form.
