Considering Kairi, Riku AND Sora all have wielded Keyblades, who's to say Riku and Kairi won't be playable characters in KH3?
Imagine, certain parts of the game, you'd play as Kairi 'cause of a story element, or maybe you could choose who to play as. Different abilities, strengths, and weaknesses, and whatnot.
But, yeah, there's my main point. Playing as Kairi, Riku, and Sora. I mean, they already have three different playable characters for BBS, right? Why not for KH3? And, to extend that concept, co-op, like how Limex stated:
Player 1, Sora.
Player 2, Kairi.
CPU 1, Donald.
Or even,
Player 1, Riku
Player 2, Goofy
CPU 1, Sora
Just think of the combinations. And now that I think about it, PS3 can support up to 4 players right?
Player 1, Sora.
Player 2, Goofy.
Player 3, Donald.
I don't know what Player 4 would do, but think about it. That'd be kinda cool, right?
