There's a summary for the Ghost episodes. I hadn't noticed it yet.

It also teases a certain other Rider and the end of the description really seems to be suggesting a rather big development in the show.

The "Ghost arc" starts with Another Ghost stealing a person's soul. Sogo who witnessed the incident turns into Kamen Rider Zi-O and challenges Another Ghost, but Another Ghost escapes. Takeru and Narita, who appear there shouting "Kamen Rider!" restrain Sogo with a rope. They take him to the Tenkuuji Temple.

In the Tenkuuji Temple, Takeru, Narita and Shibuya reveal that they're investigating cases where people are attacked by Another Ghost as the "Mysterious Phenomena Research Institute". According to Takeru and others, it seems like someone calling themselves a "Kamen Rider" appeared in the locations where they attempted to catch Another Ghost. They thought that Zi-O was that "Kamen Rider" and Another Ghost's underling.

It's a story that begins from a misunderstanding. When Another Ghost is created, Takeru loses his memories of "Kamen Rider" and misunderstands the situation. However, that Kamen Rider isn't Zi-O. So, who is it? What's their connection to Another Ghost?

And furthermore, how does Makoto become involved with Takeru and the others in episode 14? One wonders if it might suggest the revival of Kamen Riders Ghost and Specter.

That's an official summary hyping the episodes. There's no reason to throw that bit at the end unless it's actually going to happen.
