When She-Hulk aired in 2022, Marvel had no plan for a standalone TV franchise within the MCU. It was only in October 2023 when the idea of Marvel Spotlight, a standalone banner for mature and grounded superhero stories could be made.
It is currently unclear. Brad Winderbaum, producer of the Echo (2024) series had stated that the show will continue the storyline of Daredevil (2015). However, given the lack of correlation between the Defenders Saga and the general MCU throughout the years, it is unknown how the storylines will be made connected.
