Tsukasa's sister will appear in the movie.

Grandpa Hikari is Shinigami Hakase. Narutaki is Jigoku Taishi

Zol Taisa is rumored to be played by Gackt.

Shadow Moon takes Tsukasa's place in the DaiShocker hierarchy.
Unlike the original King Dark from Kamen Rider X, the movie's King Dark II is human-sized.
The movie will take place in Decade's World.

There will be two "Ridermen". One is the heroic Kamen Rider. The other is a scientist working for DaiShocker.

The Showa Riders are also alternates. Same first names, different family names.

When Decade achieves Complete Form, not only does he gain the Final Kamen Ride ability, he also unlocks the other main Heisei Riders' potential to "evolve" into a new form

Also, images of Decade Complete Form:

Spoiler for Decade Complete:

Can't say I'm terribly fond of the complete form, though it wouldn't look half as tacky if only the Kamen Ride cards weren't there
