Yeah, while at it here is how I think the meddling of Foundation X in the shows they are not mentioned would have gone down and if I was the creative staff:
Wizard: Funded you-know-who with the big ritual in the beginning
Gaim: Funded Yggdrasil with tech development
Drive: Funded you-know-who with Roimude development and also influenced you-know-who's descent to madness
Ghost: Funded Ganma leaders and promised them this and that, etc. Responsible for instigating the demise of Ryu Tenkuuji
(sorry the only thing I care about in this show were the mishaps and antics of Onari :lolol)
Ex-Aid: Endorsers of Masamune and GENM CORP.

Well, here's a possibility, however remote:
Connected universes are a potential goldmine as the Marvel films have shown. Everyone is trying to do them - toy companies like Hasbro are trying to mash Transformers with G.I. Joe, M.A.S.K., Rom and Care Bears (or something), Universal keep trying to connect their classic monsters and the American Godzilla franchise has mixed with Kong and teased Mothra and King Ghidorah.

We know Toei gets this as their new Space Squad connects most of their Metal Heroes and Dekaranger. I wouldn't at all be shocked if they didn't attempt a partially unified Riderverse.

They have loosely formed it all these years for crossover sakes but yeah I think it is time they do it if they are serious.

Not everyone can succeed. DCEU, Monster Universe, Sony Spider-Man, and a few more failed miserably either by critics and/or box office. Only MCU and Star Wars manage to succeed. W did some ground laying, but each and every succeeding series tries to do their own thing. The movies sometimes are canon and non-canon. However, Toei only cares about toy sales. I mean DBSuper upset a lot of fans because of the bad storylines and arts. A lot of the actors aren't hardcore toku fans and only see it as a stepping stone for better acting career since it's exhausting to work all year long with minimum pay. Sometimes, they do return like Faiz and they try to connect his series' ending to the Taisen and KR4, but it created more questions and continuity errors,

Star Wars didn't succeed in that regard because it didn't do a cinematic connected universe that the MCU popularized, it just had one story with this one big world

Cranejoe updated his list of the Q1 toys with a bunch of details. Some of the more important ones:

-The Transteam Gun is the transformation item of Nightrogue and Bloodstalk. It apparently yells out "Mistmatch" for transformation, which is my favorite fucking thing. It's the perfect mixture of playing off Build's "Best Match" thing while at the same time incorporating the steam theme. Oh, and the Bat and Cobra Full Bottles come with the Transteam Gun and Steam Blade, respectively.
-クローズ uses the Build Driver.
-There's gonna be a couple of campaigns, the first one for the Build Gashat when you buy the Build Driver. The second for some poster and the last for the Lock Full Bottle when bought alongside an unspecified toy
-The Cleaner, Hedgehog, Fire and Lion Full Bottles come with the Bottle Holder, Drill Crusher, Pandora Panel, and Build Phone, respectively
-The Pandora Panel holds 10 Bottles. It is apparently a key item
-The Build Phone is a smartphone that turns into a bike

Neat stuff.

Probably Build Phone is like Lock Vehicle.

As this will be the last rider of the Heisei era this could tie up the whole Foundation X plot line. That or the next rider who will transition between emperor.

Sooooo....how long until we get into the cheesy puns for this series?

These leaks are really building up hype
