So I'm guessing different dinosaur modules equal different forms/stamps?

It almost looks like a manga doodle with all those dots.

The rumored collectible for Revice is stamps. Each stamp will be an animal fused with a Legendary Rider.

the powers of Kamen Rider Decade are linked to a shark stamp.

I just now realize the joke... Decade's a CARD Shark!

How do we know that Legend Rider Powers are involved, and if we actually do, then which Rider is Revice based on?

A 5chan post from about a month ago claimed it with Revice's logo and Driver using the number 50 in their designs, it also called Decade's item being shark themed, which seems to be the case with the colouring and pattern. As for Revice himself, there's a chance it's his original item like how Zi-O has forms that aren't based on other Riders

Stamps I can get behind...but why infuse Legend Riders into them?!? Is it because it's the 50th anniversary of Kamen Rider?

Why else?

Based on the fact it's a shark that sort of kind of looks like decade, I think it's going to be a much more subtle reference than something like Zi-O

I'm imagining the shark form for example will be a brand new suit that really just looks shark inspired just with Decade's colour scheme and maybe a decade reference of some sort in the jingle?

Like this is just speculation on my part, but the actual shark stamp toy is just so subtle a reference that I can't imagine he just turns into a totally decade themed form

If it's something like Zenkaiger or even more subtle I think it'll be fine, personally I don't want something as overt as Zi-O/Decade/Gokaiger, especially since there's only been two shows between Zi-O and Revice

Yeah, I feel like having more subtle references would work well for this season. The forms could even have finishers styled after the Kamen Riders they are modeled after.
