You are most welcome, J. (Mind if I call you J?) A few thoughts and additions of my own:

No, it has not been confirmed that Isabella was a playable character, though it was confirmed that she appears in the game, first by Dana Allyn/DragynAlly's comments on her YouTube video of footage she took at Disney's New York event and by Alyson Stoner being listed in the cast announcement in the official press release. This is visually confirmed by the video itself, since although we cannot hear the in-game dialogue since the Disney rep skips through and/or talks over it, we can see Isabella's face as one of the faces representing who is talking on the subtitles for said dialogue. The Disney rep also stated the other playable characters are "agents", which to me sounds like it refers to OWCA agents, though it could mean "agents of the resistance." Also, besides the original creative content and voice talent being contributed, we now know the series creative team contributed an original song to the game, which I assume is the one heard in the trailer.
