So... Zi-O's getting a mech?! Possibly a transforming one, though I have no idea what that thing in the corner is that it folds into? It's not his bike because...
The bottom of this page has the first look at Zi-O's bike (or at least the toy of it). It seems it changes from a Ride Watch, kind of like how Gaim's bike folded out from a lockseed.
At the top of this page is Gates' axe/bow weapon, the Jikan Zax.
Then, a surprise! The Decade Ride Watch is larger and has the ability to attach other Ride Watches to it. It also gives Zi-O a different sword weapon, the Ride HeiSaber (yes, a Heisei/Saber pun).
I guess it makes some sense: Decade also had the ability to turn into other Riders, and Zi-O will be airing when we reach the 10th anniversary of when Decade began airing.
I've no idea what the cylindrical thing at the bottom is, but above that are more legend Rider Watches.
Top row, left to right: Ryuki, Faiz, Fourze, Kabuto, Hibiki
Bottom row, left to right: Wizard, Agito, Gaim, Kuuga, Double
More Ride Watches. The top row are ones we have seen (Build, Ghost, Drive, Ex-Aid).
I'm not sure about some of the ones on the lower row. Faiz Accel? Kiva? Then Blade and OOO.
Weirdly, they're bringing out toys based on the gear of old Riders - the Faiz Phone, OOO's Hawk Candroid (or possibly Wziard's Garuda Plamonster?), Gaim's Watermelon Arms.
They are also releasing a line of "Rider Kicks" action figures. There are two kinds. the first are Zi-O's forms based on previous Riders: Ghost, Ex-Aid, Fourze, OOO (complete with full cheetah!) and Decade. the second kind are just figures of Riders from previous series (the picture shows all the Build Riders plus Ex-Aid).
The Jikuu Driver can rotate 360° on it's base. Doing so seems to activate a "Time Break", which I'm guessing will be the finishing move?
At the bottom is part of the transformation sequence. If that's meant to look like the actual character, I guess at the least we can rule a girl out?!
A slight clarification: This larger view of Gates' Driver shows that the date displayed on the screen in 2068, not 2066 as mentioned before.
