Yuto looks different because of the different hair color. Is that really him? I'll need to rewatch the trailer again, I seem to recall him having his original hair color in that scene with Deneb. I thought it was Hajime.
It seems to me that they might be going the "alternate history" route they went with in LGKR. Doesn't sound thrilling, but I like the new monster which looks like it truly belongs in the 70's, and Shocker seems to have a strong presence and a more dignified treatment.
I like that Blade is captured by Shocker, I really like it when a Rider gets connected in some way or another to another Rider's enemy. And this sentence sounds wonderful: "Garren, Mach and Zeronos break into Shocker's base to rescue Blade."
Given the scene in which the Blade trio apparently attack Zeronos makes me believe that for some reason or another, Blade is rescued, then he Leangle (who seems to be aligned in some way or another with Shocker) and Garren betray Zeronos and Mach and attack them.
Of course, it's all part of some masterplan.
It's inevitable for me to immediately go for Shirakura-inspired low expectations, so I hope my prediction is wrong.
And they finally mentioned BLACK RX and acknowledged that he is the other car-driving Rider!
