September is when we usually get the copyright, it's just under a year since Zyuohger. This a chart of major dates for past shows:

Huh, interesting that Nininger had it filled out later than the other series.

maybe it is space / police combo

start 5 members
and 6th member be their mentor
and 7 & 8 members be twins
and 9 member start as bad guy and then he turn good

vilians be under ground spider empire
spider bite make monsters grow

Can't wait to see what the suit designs and mecha designs.

"She is the one named Ranger Moon" 😀

A Space Themed Sentai sound like a refresh Sentai show because it's NOT another Dinosaur Sentai or another Ninja Sentai.

This could be a TRUE Sci-Fi Sentai show because Kyoryuger and Zyuohger was a mix of Fantasy and Sci-Fi while ToQger and Ninninger was a Fantasy one with little bit element of sci-fi stuff

maybe their suits be mix of dekaranger / fiveman

I'm not forcing anything, I'm making a casual observation. So you can unbunch your panties. ;)

We don't have any information so far. We don't even know that Kyu means 9 in this context. So maybe let's not be so rigorous about people's idle speculation. :rolleyes

Here are my speculations:
Depending on the kanji kyu can also mean ball or orb, hence Chikyu meaning Earth.
Planets are round and I have a feeling if the above is what they intend orbs will be the key item. And I will not rule out the possibility if the roster being 9 ultimately yet.We could get a Kyoryuger pulled on us.
