After rewatching the trailer, I suddenly thought of something. It seemed really obvious, and I'm not sure why I haven't heard of this idea before.
What if the plot of DDD is basically Sora and Riku (Maybe Mickey too) going after clones of Xemnas and Ansem SoF, who were created due to Xehanort being recreated. So basically, there are a bunch of phantoms of Xemnas and Ansem SoD going around causing trouble, but Sora and Riku can't do anything about it. So they have to do something (Travel to a parallel dimension, go to sleep, it doesn't matter) that temporarily allows them to face Xemnas and Ansem. Once the Drop Gauge runs out, they have to leave, or it swaps between Sora and Riku, something like that. Every world would end with Sora facing one, while Riku faces the other.
At the end, beating all these phantoms leads to the original Xehanort (In Terra's body) reforming, but they decide that there was too much risk in letting all those Xemnas' and Ansem SoD's stay around.

Cue KH3.
I dunno, sounds pretty plausible to me.
