all my yes!!!

Here's my analysis of the historical figure of the new Eyecons:
Himiko - shaman queen of Yamataikoku.
Sanzo - Japanese pronunciation of Xuanzang, a Buddhist monk who traveled from China to India
Ishikawa Goemon - a Japanese ninja/outlaw who is the subject of several kabuki plays
Ikkyu - Japanese Buddhist Zen monk and poet
Sakamoto Ryoma - Japanese politician who wanted to modernize Japan during tbe Edo period
King Kamehameha I - Hawaiian king who unified the Hawaiian islands
Grimm? - Can refer to Jacob Grimm, Wilhelm Grimm, or both, German brothers who wrote many popular fairy tales such as Snow White and Rapunzel
Galileo Galilei - Italian astronomer and physicist who supported the heliocentric theory
Charles Darwin - English naturalist who created the Theory of Evolution
Pythagoras - Greek mathematician who discovered the Pythagoream Theorem to find the sides of a right triangle
Florence Nightingale - English nurse who founded modern day nursing and helped those injured in the Crimean war
Christopher Columbus - Italian explorer who accidentally landed in the Americas on a journey for Spain
William Shakespeare - English writer who wrote many famous plays such as Romeo & Juliet and Hamlet
Napoleon Bonaparte - French emperor who was prominent during the French Revolution
Santa Claus - No explanation necessary
Leonardo da Vinci - Italian Renaissance artist, inventor, scientist who made several contributions to the modern day and painted the famous Mona Lisa
Shotaro Ishinomori - Japanese manga writer and the creator Kamen Rider

The fact that there are a couple of eyecons from female historical figures, could be a hint to a female rider...

I'm not so sure female Eyecons explicitly mean a female Rider. OR that Boost is a third Rider entirely. The reason I say that is because Specter has his own standby jingle opposed to Ghost's, and all of those mentioned Eyecons begin with Takeru's standby. I think Boost might be a super or final form.

I don't think so, honestly. Because based on Musashi and Edison's mannerisms, I still get the impression that Takeru is possessed by each soul, so I'd want his final to be a progression of Ore personally. The Ishinomori Eyecon would be a perfect way to introduce the "Kamen Rider" title though. Like, he's just simply called "Ghost" up until an arc where he comes across Ishinomori's soul. After learning about his work and using his Eyecon, Takeru decides to accept the title for himself. If not that though, I have a feeling it will just be a movie exclusive form.

Okay, I love the Nightingale and Kiva sounds

Nightingale has an ambulance-like sound and Kiva is Kiva.

Eat your heart out Assassin's Creed.

Spectre's Eyecon does, but we can't really hear what jingle Nobunaga and Tutankhamen had. Even if they do have specialized jingles for each Rider, though, that wouldn't necessarily exclude any of these Eyecons from belonging to people other than Takeru. Like...in addition to more Riders, we're more than likely going to get another Driver. So maybe the female Rider has some other spooky Driver and uses those Eyecons with that. They would still have programmed sounds in the Ghost Driver, though, but since she wouldn't use it she wouldn't get her own jingle.

It's true that maybe since Takeru might be the first user of the Driver, his own soul's standby jingle is the same as the default one. What makes me think otherwise is that the closed lens of Specter's Eyecons are a different color than Takeru's. Maybe the Eyecons have some kind of link to the first Rider who uses them? We just don't know at this point. Perhaps you're right though and they will often swap Eyes with each other. I find it strange that whoever recorded these just so happened to skip the jingle entirely on both Nobu and Tut. Provided I'm right and those do have Specter's Jingle however, based on the skipped standby and the tone of the voice, I have a hunch Grimm will be one of Specter's forms too. But who knows?

I don't quite agree with this either for a couple reasons. First, that assumes a second Driver would use anything like Eyecons at all, about which I remain skeptical. Second, if that were the case you'd think there would be more Great Women Eyecons. I somehow doubt they'd miss the opportunity and pass up things like Joan of Arc, Amelia Earhart, or Cleopatra. That said, if any of those sounds are found in the future, I might be convinced.

This is very exciting, I can't wait to see the Ishinomori form, and the others sound great. Lol My friend was saddened to learn that Santa Claus is apparently dead lol.

Wow been a while... So much cool info.

Okay I'm still calling this as a multi rider series on this time they're keeping a lid on it. The fact that both the main rider and secondary rider use the same driver and whose suit aren't very different from each other leads me to believe they're going the multi-rider path but I'm thinking a rider roster along the lines of Kabuto rather then Gaim. And if they have a female rider I bet she'l be pink with heart shaped eyes and short 'cute' horns.
