You know what would be cool if Decade comes into English? Who knows... the Japanese version's story didn't quite impress me.
Dragon Knight:
- New Riders: A spider, buzzstinger, Fenghuang including Including Abyss (shark)
- A new enemy approaches
555:
- The Orphenoch king returns. New Orphenochs appear: Tiger
- New Riders: Maybe Sigma, Epsilon
Blade:
- Kenzaki (or English Actor) returns as the Navy Joker. Hajime tries to save Kenzaki from the same fate he had.
- Glaive, Lance and L'arc are sent by the new BOARD to hunt down Kenzaki, because he is the new Joker. A new Battle Fight will appear.
- Perhaps Garren/Galleon and Leangle might unlock their King Forms for the first time.
- Undead that haven't been unsealed: Frog, Whale, Fire, Tornado, Blizzard and some of Leangle's cards.
- Paradoxa Undead, who is once Kamen Rider Abyss reveals to be the new BOARD chief and his plans are to seal Kenzaki and ensure that Blade is out of the way
Hibiki:
- The Oni from the Finale episode appear
Kabuto:
- New Riders: A new Beetle (probably Atlus) Including two Spiders: A black widow and wolf spider
- Kabuto returns and the new Beetle rider turns out to be a Worm
Den-O:
- Ryotaro faces an alternate version of himself with good luck.
Kiva:
- Wataru rules as the Fangire King. Megumi becomes Saga. Maybe a new Fangire queen will show?
- The Neo Fangire arrive featuring the Beetle Fangire. Well... what would a Neo fangire look like to you?
