The form debut timeline we saw suggested as much, although it's less clear about Fourze than it is about Build and Ex-Aid appearing early.

Probably the less surpising, but 555 and Kaixa actors mentioned on their twitter they are done filming "something".

Kamen Rider Decade & Den-O Won't Be Appearing That Easily in ZI-O
 

The Faiz Ride Watch are in first toy quarter so its possible we has faiz tribute episode.

I know it has been a while, but Katsuhisa Namase will be playing Sougo's grand-uncle in Zi-O and never have I thought I would see the day where THE VICE PRINCIPAL OF GOKUSEN will play the Tachibana of a Kamen Rider show. Naoto Takenaka being on Kamen Rider Ghost was already shocking enough a few years ago, now they bring in another versatile actor who played the lovable-yet-annoying vice principal from Gokusen. He was also grown-up Donkey from 20th Century Boy.

It was announced that Zi-O is getting a spin-off already....? Jefusion is the source of my info, here's the article. Lol

But after reading the article it doesn't feel like a spin-off. More like an extension of the episode. But then again, who knows.

Say what you will about Faiz, I love that the actors come back so much! Can’t wait to see Takumi suffer more.

Bandai just announced they will release a CSM for Kuuga's Arcle Belt. Does it mean we can hope that Joe Odagiri will finally comeback?

Probably not. Would be great if he could make it but probably not. And I honestly would like them to just include the sound effects and the background music from the TV show and call it a day.

For Zi-O? No. He doesn't hate Kuuga, but he does hate Tokusatsu - Kuuga's just the exception that he does like. He has said he'd consider a Kuuga reunion show if the director and writer returned for it, but not a crossover, or anything to do with the larger Kamen Rider franchise.

All 19 Heisei ride watches are first quarter from what I remember in the scans. So while this may be promising, there is a chance some riders wont get to appear or do so only in minor roles instead of getting the whole 2 episode arc.
