Oh shit, so there's gonna be a Zi-O Trinity which fuses them all and Grand will be themed after a Buddhist altar. I NEED to see this, that sounds TOO ridiculous

Bandai don't do that, though. Look at Build, and Ex-Aid. Ex-Aid's Quarter 3 gave us the Parablay Gun, the Buggle Driver Zwei+Kamen Rider Chronicle, Tokimeki Crisis, and Hyper Muteki...and Build gave us HachiMarine, SaiDryer, BatEngine, the Evol Driver, Evol Dragon+Evol Rabbit, Cross-Z Magma, and Build Genius.

Build and Ex-Aid both also had really packed 1st and 2nd Quarters too - Build especially.

This is the smallest final push for a Rider show since Ghost, which only gave us Mugen, Deep Spectre, and the Deep Slasher.

Since Build didn't get anything for Quarter 4, which is almost always for movie-exclusive stuff (the only exception I can ever recall is Brave Legacy being in Ex-Aid's), I wonder if Zi-O will.

So, is there going to be a Kamen Rider Ginga then? (flashbacks to Ultraman Ginga)

No, it's the 'Woz Ginga Miridewatch', not the 'Ginga Miridewatch for Woz'. Like Geiz Revive - it isn't based on a Rider, but is a standalone form for Woz.

...I stand corrected, re: Ginga.
Although that begs the question of why is it called the 'Woz Ginga Miridewatch', when the others are just 'Shinobi Miridewatch'.

By rider you mean the 19 previous Heiseis, correct?

Chaos Entity is talking about Woz Ginga so no

Am I crazy in thinking Zi-O Trinity looks far better than Grand Zi-O?

Nope, Zi-O Trinity makes clever use of the fusion idea and the katakana gimmick while the Ridewatch itself is pretty unique, especially with the image of the 3 Riders and Zi-O on the throne. Grand is something we've seen before and incredibly gaudy, which isn't for everyone
