So he's a robot physicist that uses a 3DS touch pad on his belt to henshin.

Oh, how I would support that!

I think Gaimu sounds much like Game?

I'm pretty sure it'd be pronounced "guy-moo". It would probably be romanized as "geimu" if it were supposed to mean "game".

I'm totally down for that.

Interesting, but the name doesn't mean all that much to me without knowing more about him.

To me it is like swapping armor parts and change battle style.
Of course Gaimu itself could be a guy's name. Pretty chuunibyou-ish name.

EDIT:
Another rumor from 2ch saying there is an unknown Rider wielding a green and black katana, while staff has a white katana in hand during the filming of Wizard's summer movie.
Coloring of the katana(s) are using W and Fourze's color scheme, suggesting this new Rider has the ability to make katana out of other Rider's power.
Gaimu will start in October. W, OOO, and Fourze will show up one at a time near the end of Wizard for a month before the launch of Gaimu.
It will be something that will work like Decade. This might be what Morimoto Ryouji twitted about earlier, about something that may drive Rider fans nuts.
Decade may show up as well.

Also gather 4 Rider tickets for vinyl set...?

I just hope it has nothing to do with break dancing, mini discs and ghosts because that shit sounded DUMB.

Gaimu..鎧武 (Armored Musha).. I think it will be kind of samurai version of Kamen rider or something.
maybe VS Samurai sentai shinkenger will be fun, but we know that's not gonna happen.

If that Kamen rider is really "Samurai Concept", It can't not be release on South Korea anyway.

Hmm, interesting...

IF it is a anniversary show, I hope to GOD it turns out better than Decade. Oh, and this is my personal bias, but I hope Naruhisa Arakawa is the main writer on the show, because to me; there is no better way to commemorate an anniversary of the Heisei series than by getting the main writer of the first Heisei Rider show (Kuuga) to write it.
