In the recent article, we came to know that Zenkaiger will go on hiatus for making way for the Olympics broadcast. Though we didn't know the details of Kamen Rider Saber at that time to confirm on Kamen Rider Saber's hiatus too. But the new scan from Uchusen magazine leaked confirms that even Kamen Rider Saber will be put on hiatus.
Currently, it's only known that both the show won't be broadcast on July 25. So considering the Olympics dates probably the hiatus might last for three weeks. That is there will be no Super Hero Time broadcast on August 1st & 8th. But it is yet to be confirmed for these two dates.
This hiatus will also make us recalculate the possible number of Kamen Rider Saber Episodes to 46 instead of the previously assumed 50 Episodes.
Other than the news about the hiatus, Kamen Rider Saber Episode 42 & 43 which are going to air on July 4th & July 11th respectively are directed by Kazuya Kamihoriuchi and is written by Takuro Fukuda.
On July 18 instead of the regular Kamen Rider Saber, Zenkaiger airing there will be a special broadcast titled "Movie Release Commemoration - Combined Special" which is directed by Satoshi Morota & written by Nobuhiro Mouri. As of now, this is believed to be 1 hour TV Crossover Special like "Shuriken Sentai Ninninger Vs Kamen Rider Drive" & "Ressha Sentai ToQger Vs Kamen Rider Gaim".
