Anything could fail at any time, its the nature of the universe.

You asked this twice, theres no reason for that. Wait for an answer. If it does not come, you've been ignored.

You've also made multiple posts in a row again. You can just edit your last comment to include the new thoughts you have, theres no reason to double post.

This is not a Discord chat, no infinite scroll, theres a page size limit and constantly double posting and asking the same question multiple times after being ignored or having to wait means that each page is half full of your short comments and i have to scroll through more pages to follow the actual conversations going on. Its disrespectful to all the other people who want to have their comments seen and replied to as well. Multiple questions or comments are fine, but do it all in one post.

To actually answer one of your questions:

They already said they are deep into working on the show for after Gavan, and it will be even less similar to sentai, and thats pretty much all we know. But like has been said, anything could happen. Like we talked about before, it was announced alongside the release of Zeztz that there would soon be Zeztz, a new sentai, AND a new toku show (presumably SSS:Gavan Infinity) all airing at the same time. That changed within a matter of i think a month or 2, smashing 50 years of precedent. Its a new era, prepare for surprises.

For sure, Geki developed a lot through the movies and soon it'll be 8 years since his last appearance, he could totally fit in the mentor role. This would be a great opportunity to bring back Space Squad, since he's the leader of that project. I can see that being used for the summer movie, with some past Metal Heroes and Rangers showing up.

Toy listings have confirmed the three suits in the trailer are for three separate heroes: Gavan Infinity (Red), Gavan Samurai (Silver), and Gavan Hikari (Gold). The gimmick will be a gun and battery combination kinda like Kyoryuger. Guns transform into the mechas, and can combine with auxiliary mechas.

Anyway, I've already been answered, but to be more specific, I'll recall the situation with the Kamen Rider revival in the late 80s. Back then, despite Black's strong start, it all ended after just two shows. Yes, it was a different time and a foregone conclusion, since Toei was competing with itself, making projects for different channels. But they still decided to bet on a more stable franchise.

With names like those, they should definitely team up to form Infinite Samurai Hikari, like Zi-O Trinity. Overall, judging by their names, I'd venture to guess that Samurai will be a more seasoned veteran hero, a mentor, or a grumpy retiree. And Hikari will be a mysterious leader.

What people need to keep in mind about Project R.E.D. "failing" is that for Toei to change course and and say pivot back to super sentai Project R.E.D. would not "just" need to fail... it would have to "SPECTACULARLY" fail.

Ratings and merch sales would have to be below what Super Sentai has made in the past few years. If lets say Project Red does the same as Gozyuger then they will stay the course because there's always a chance it could get better and according to recent interviews they seem to have an "at minimum" five year plan of worldbuilding in mind.

Furthermore from what I understand I understand what sold the most in the Super Sentai merch was the Roleplay Henshin Devices while the rest of the figures and "Zords" sold poorly in Japan.
And if the Toy listing leaks for Gavan Infinity are true The toys are the gun (which is said to be the Henshin Device) Robots that transform and combine with the gun and batteries you insert in the gun to make different sounds.
This is a clear indication that they are hedging their bets and are backing what they belive to be a winning marketing strategy.

Now, will it work? Only time will tell.

But failure seems unlikely, again, failure being PR performing worse than SS. if it performs as well as SS then they can just coast and try to retool the show until ratings/sales improve.

Yes, and yes. This time, the plot will be Minoru and Signalman's Excellent Adventure II: Electric Boogaloo, where Minoru sends Gavan Infinity's new weapon to Bug Naraku by mistake. :lolol
All joking aside, I think a new Space Squad movie or mini-series is something they should push towards.
And assuming they'll take notes from Shaider and Spielban as well, perhaps the main toy of the show could be a cross between Gaburevolver and Tega Sword. Also, assuming they go Gavan-verse with this show... OPEN THE FAN-CREATED GAVAN FLOODGATES. :rock:
I seriously hope Gavan Samurai gets an episode where they go full Kazuo Niibori complete with sunset and katana-wielding fight choreo.

Yes, I also wrote earlier that Toei is doing everything possible to make Infinity Gavan a commercial success, even if the show itself fails. But still, it's worth remembering that Super Sentai is an iconic, long-running franchise with enormous cultural influence. And their failures are unattainable for most tokusatsu shows (KR doesn't count). Plus, I think some adult fans who've cooled off to tokusatsu but continued watching out of habit might use this as an excuse to stop watching. Basically, life is unpredictable, so it's best to hope for the best and prepare for the worst.

I think a true worst case scenario would also have to account for if R.E.D. goes down and Sentai is just not ready to go, which from a production standpoint I would not expect the idea of a new Sentai to be ready for at least 3-5 years, Toei would probably do anything besides a new Sentai or new hero show while still holding the time slot. If anything, we'd be more likely to see the return of the Fushigi Comedy format in the event of an immediate catastrophic failure than we would the return of Super Sentai.

Much like how Metal Heroes essentially became retooled into Fushigi Comedy shows with Kabutack and Robotack. Moero!! Robocon replaced them as a stop gap after they collapsed in popularity, but Kamen Rider Kuuga wasn't ready yet.

Worst case scenario is this fails and Toei rearranges the timeslot, and reformatting Super Hero Time as just Kamen Rider and Precure.
