I have a feeling that the connections are mostly aesthetic. Fourze's Suit, with some exaggeration, could be made to look like a Gorilla. However, there are connections otherwise. Like how Eagle Genomes Revi having a Trenchcoat is meant to reference a cut concept that Double's Forms would have a Trenchcoat. Ptera Genomes has a major connection in that both have a Rider Machine that has a humanoid form (Vice vs the Auto Vajin). The Ptera Vistamp's connection to Faiz is that Faiz Axel can be combined with a Pterosaur. Meanwhile, Eagle Further connects to Double in the Xtreme Memory being a bird and the term "Eagle-eyed", meaning having a good eye for detail. Kong further connects to Fourze in the fact that Apes were the first major creatures launched into space and that gorillas can create large friend groups, like Fourze did. Kamakiri connects to Gaim as the two "arms" of the Praying Mantis resembles the way that Gaim duel wields the Musou Saber and the Daidaimaru. The Mammoth connects to Den-O in the aesthetics of the Sword Form DenKamen having metallic parts that resemble Mammoth tusks. Heck, even Megalodon can connect to Decade as both are passing through wherever they are (Megalodon passes through the sea, Decade passes through alternate worlds).
In fact, there are extinct species of all the animals on the Vistamps. The Haast's eagle, the Gigantopithecus (a Gorilla-like ape), the Barbary lion, heck even the Jackal is able to be connected to an extinct species known as the Arno river dog. There is an extinct version of the Mantis as well. Meaning that the animals on the Vistamps can be equated to an extinct animal.
Another connection to the Jackal can be seen in the 3 Species of Jackal, the Golden Jackal, the Side-Striped Jackal, and the Black-backed Jackal. The Golden Jackal can connect to Hyper Muteki, the Side-Striped Jackal can connect to Standard Ex-Aid, and the Black-backed Jackal can connect to Gemn.
Meanwhile, Brachio Zi-O is reportedly going to be the Mech Form for Revice, which connects to the Time Mazine AND to the Dai Mazine. The Batta Kamen Rider 1 Connection is pretty much the only direct connection. The others can be figured out via analyzing the connections.
So, via analysing the connections, I have some assumptions I can make. Wizard will be connected to Owl (as the rumors/leaks say) because Owls are seen as creatures of wisdom and magic, commonly connected to wizards. Aesthetically, Wizard's Head looks alot like an Owl's Body, but also the big eyes resemble an Owls. This Form will likely have a huge cape to resemble an Owl's Wings.
Drive could be connected to Chameleon (because of the looks), but also a Wild Boar. Those tusks on Wildebeest can resemble Drive's face.
Ghost would likely be connected to either Iguana, because of the Iguana Ghoststriker, or maybe Narwhal.
Hibiki would likely be connected to the Spider Vistamp that has been shown off. As a spider's legs can be translated into Hibiki's head. And it connects to Tsuchigumo, a monster from Hibiki (well, a large amount of the Giant-type Makamou are Spider-based).
Kiva could be linked to a butterfly, of all things. Because the faceplate of Kiva could either be a bat or a butterfly. And the multicolored stained glass-like appearance around the Fangire and when Kiva is bitten by Kivat-Bat the Third, is another connection. Also, the fact that Butterflies metamorphize using a cocoon can connect to the final part of Kiva's Transformation Sequence as the suit finally is revealed AND to the Wake Up Finishing attack. Man, Butterfly Genomes being Kiva-themed sounds pretty cool.

Just like Revi and Vice, it seems Juiio and Olteca also based on animals and Legend Riders.

Wolf + Kamen Rider Kabuto (beetle) = Julio
Octopus + Kamen Rider Ghost (hoodie) = Olteca

Also, both Kabuto and Ghost were seasons that fell on anniversaries (35 and 45), so it’s pretty clever that they get some focus.

I question how Agito, Ryuki, Blade, OOO and Build will be used. What animals and dinos would fit them? Will we expect new Deadman generals soon?

So, I have read here (https://www.youtube.com/watch?v=QLBON-CePqs) in the comments that the Revice Driver Stamp Part is detachable. Anyone able to confirm that?

Here you go. The stamp part is just a magnet board anyway with lights in it, nothing too complex so it's pretty easy to remove. Maybe for a future upgrade?

I just saw a picture of the "Strange Driver" on Kamen Rider Wiki.

How similar does it look to the buckle with 71 on it?

Wonder what the Deadman generals' names mean? Olteca is in question.

It's definitely a reference to something like the Aztecs. (It might be a reference to the Aztecs, but I know there were other ancient societies somewhat similar to them.)

Julio and Aguilera are common name and last name, respectively. I'm not exactly sure about Olteca, who is just 1 (japanese)character away from "Ortega", but I read somewhere that the 3 of them are a reference to liquor brands or something
