Here’s hoping so, after Wizard dropped the ball.

I seriously doubt that.
I'm betting it'll be a new WRB along with a new emblem for the Seiken, instead(and even that's a stretch) They can't even bother to sell or advertise weapons for first quarter upgrades. Extra weapons are starting to feel more and more like the Ride Boosters from Drive - it doesn't help that the Dragonic and Lionic Boosters are extremely reminiscent of them lol

No, we're getting a new sword for the final form. Within the shows mythology, Rekka will eventually create a new sword once it's powerful enough.

I mean given the idea of Rekka evolving, a new emblem would be neat but kind of boring if it's just an emblem swap. Unless it's like an emblem and attachment to make Rekka itself cooler.

And there is stuff about how there's another blade besides Caladbolg that Logos should have gotten if Touma didn't interrupt the ceremony. So I'd say our chances are in the mid to possibly high ranges of a new sword/weapon for the final form happening.

What episode was this from?

Personally, I kind of like Kamen Rider Solomon's design. It is very much stitched together from other suit parts. It has the overall body from Kamen Rider Zi-O's Kasshine (the Bird/Cuckoo Clock-based soldiers of Ohma Zi-O, Barlckxs, and Another Diend), the Head from Kamen Rider Calibur Jaou Dragon Form, the Cape from Kamen Rider Gaim's Kamen Rider Bravo Kingdurian Arms, the Caladbolg is based upon the Kingexcalibur (fitting, since in the King Arthur Mythos, Caladbolg was the original mold), the Driver/Belt is yet another Jaken Caliburdriver Redeco, and the Omni Force Wonder Ride Book is a redeco of the X-Swordsman Wonder Ride Book. The Omni Force Wonder Ride Book is based upon an Omnibus, which according to Google's Dictionary, is "a volume containing several novels or other items previously published separately". Which is fitting for his suit, which is a combination of several items previously released separately. Meanwhile, Kamen Rider Solomon is freaking overpowered as heck. It could handle Kamen Saber Elemental Primitive Dragon, Kamen Rider Blades Tategami Hyoujuu Senki, Kamen Rider Saikou X-Swordsman, Kamen Rider Slash Hanselnuts to Gretel, and Kamen Rider Buster Genbu Shinwa all at once and basically get no damage from them all. It could negate both Kamen Rider Sabela's and Kamen Rider Durendal's Powers, those same powers requiring Kamen Rider Saber to use the Primitive Dragon Wonder Ride Book, those same powers defeating multiple swordsmen all at once. And Master Logos aka Isaac said that the Omni Force Wonder Ride Book was incomplete. Basically, it's like an Anime Villain saying "This isn't even my final form." How much higher in power could Kamen Rider Solomon get?! Where is the upper limit?! I'm getting some severe Cronus>Gamedeus Cronus/Evol>Evol Black Hole vibes and I'm not sure if I like it or not.

Though, seriously speaking, what could Kamen Rider Saber's Final Form be to take down Kamen Rider Solomon? And is it somehow linked to his popup book?

Could be that or maybe in a twist, it's Storious that gets the sword, since he seems to be plotting behind the scenes about creating the ceremony for himself, like creating another Sophia. He's basically using Isaac as a way so the heroes are distracted with him while Storious does his thing.

God I hope so. The last weapon Saber gets was a dragvisor and he and Blades barely use it as a weapon because of their nature as boosters.

I think at the very least it's a sword that can be combined with Rekka, but I would love the idea of Rekka evolving, makes the term final form to be more special.

I wouldn't mind Saber getting the Booster back in the final form, provided that it's in addition to a new weapon, and he gets to use it more than once.

could anyone see Kento dying for real this time (Only if it leads to Saber's final form)
