[Kurona]

Ones I think will happen 100% of the Riders we currently have-

- Kuuga Growing Form
- Ryuga & Dragblacker
- Dark Kabuto
- Nega Den-O
- FangJoker
- [Indeterminable amount of OOO forms]
- Fourze Rocket States

Ones I think are fairly possible:-

- Agito Trinity
- Hibiki Kurenai
- Den-O Climax


And then of course there's Riders that haven't happened yet. Bujin Gaim; Drive and Ghost each have like three possible things each; the Double Riders have four different recolours... there's a bunch they could do.
