IMDb has uploaded a "full cast and crew" page for KH3

Probably not the best source and may not even be confirmed. A few other characters as well are on there. 

Faaake.

Its probably all just speculation. IMDB probably thinks the same VA's used for Dream Drop Distance are going to be used in KH3, therefore the webpage. Its just a placeholder until the actual VA's come out and say they are involved

Not sure if this can be trusted. 

[Shard the Gentleman 2,891]

It can't. Since then, they've removed the characters and added them again and removed once more. It's slightly annoying.

Hope it's true wouldn't mind kuzco and others
