Honestly, I don’t think Sakurai has plans to do another heavy story mode like “Subspace Emissary” after cutscenes got leaked onto YouTube. It’s one reason why “World of Light” was far lighter on story and cutscenes (the other being that said cutscenes were why “Brawl” had to become a dual-layer disc which was harder for original Wii consoles to read).
Plus, “Subspace” was kind of a hot mess. As the Smash Wiki states on the “plot summary” page:
- Presumably, it is impossible to enter or leave Subspace if there are no rifts. This, however, brings up multiple plot holes.
- No rifts are known to have existed before the story begins. This raises the question of how Tabuu was able to bring Master Hand into Subspace to begin the story, or how he was able to mobilize the Army from Subspace onto the Isle of Ancients.
- It is unclear how Dedede learned of Tabuu’s nature and Off Waves, given that he would have to enter Subspace to do so (as Tabuu cannot leave Subspace).
- It is never stated or shown how Sonic ended up in Subspace in the first place, because he was not affected by Tabuu’s Off Waves.
- It is unclear how the Smashers managed to escape Subspace after Tabuu’s defeat, as all the rifts that can be traveled through had been closed.
- It is never shown how Mario and Pit moved from Skyworld to The Plain, or how Kirby and the princess he saved moved from Sea of Clouds to The Lake Shore.
- It is unclear how Snake entered the Halberd.
I will, however, point out that Sonic’s inclusion was a last-minute thing so they didn’t have time to brainstorm a way for him to show up properly.
