Shout Factory tweeted about it. I'm not sure if that's an indication that Gavan Infinity will be streamed like Zeztz, but I think there's a better chance for it.
Happy belated birthday!

My main point wasn't to say that Power Rangers was the only/main reason why Toei canceled Super Sentai. It's more of a potential opportunity. A business decision that is on the back burner.

Your point aligns well with what i was saying. Toei is likely trying to consolidate their Toku IPs and likely regret not having any creative control in Power Rangers within North American distribution. At the time they licensed out Super Sentai to Saban 1) it wasn't expected to do well and 2) the U.S. was the only superpower with the greatest amount of global soft power, and 3) The only way to distribute Japanese media to the Anglosphere is to allow American or Canadian companies to heavily edit and dub it to cater to late 20th century American sensibilities.

At that time IPs weren't as massive as the star power of a celebrity, and many corporations, even domestic ones, were licensing out their IPs to syndication or competitive networks. Now we are knee deep into the 21st century and China is a growing superpower, and Japan is a strong regional power with global soft power. The MCU has completely changed the perspective on IP consolidation (noting the messiness of spreading out IPs to competitors like Hulk to Universal Studios, and Spider-Man to Sony Pictures). The internet has completely changed how international distribution works. Streaming has also created a bubble of IP consolidation and leading to corporations merging to stay afloat.

Every other adaptation of a Toei toku property has failed, allowing Toei to consolidate their properties and have greater control over their IPs when trying to market them abroad. The only hold out in this consolidation is Super Sentai. Since Hasbro holds the licensing rights to Power Rangers and permits them to create rangers and teams without using Sentai footage, this puts Toei in a bind because 1) they cannot market Super Sentai to North America even if its a season not yet adapted, and 2) Toei loses necessary funding for their Super Sentai productions from the licensing fees charged to use Sentai footage to adapt it to Power Rangers. Thus not only do they lose a vital market to sell their IP to, they have a reduced budget for Sentai going forward. With Sentai on the decline and losing licensing sales Toei had no choice but to cancel Super Sentai for the time being. While Power Rangers is not the only reason why Super Sentai got put on ice for the time being, it is a factor that cannot be ignored.

You know, it occurred to me that this new project is probably bad news for new heroines. Sentai always had to inlcude at least one, but Kamen Rider is inconsistent with them and there's no guarantee we'll get any in whatever RED is.

Oh, I've already accepted that female representation in tokusatsu is only going to continue to get worse for years to come. I think Bandai would much rather herd girls over to Precure and Aikatsu instead.

That's a valid concern, and I don't want to get my (or anyone else's) hopes up too high. But on the other hand, Sentai and Rider both have histories of always making the red rangers and main riders male, enough that producers are probably wary of backlash if they made a season with a woman as the central protagonist. Project RED doesn't have that baggage, so it's possible this could open the door for more heroines not just in general but in the leading role!

The big rumour about this included some MagiMother looking heroine for what it's worth

Literally this years Rider cast:

Also, every Rider show during Reiwa had at least one female Rider so far...?

Maybe aside from Gavv, I actually don’t know if Jiip counts. Probably not.

+ they litteraly made a specific "girls remix" series to celebrate the female cast of Kamen Rider.

Yeah I know it is just rumors so far, but it sounds likely that Gavan Infinity is going to have a male-female hero duo. So I'm not too worried about female hero representation getting worse due to Project R.E.D., especially given we haven't had two female Sentai team members since Kiramager.

I'm not holding my breath for the possibility of a woman as the protagonist anytime soon though, even if I think it would be nice. The lead role doesn't always get the most focus in these shows anyways, so I'm not sure it matters much beyond the optics of things.

I know it's early, but how many of them are actually Riders?

Jlip is canonically male, so Gavv had zero female Riders.

This is the root cause of my concern. Female representation in Sentai was inexplicably getting worse (which made the Imamori scandal sting a bit more).
