OK. It's true. I know nothing except this:
They said there would be more characters.
However, I'm looking at the writing on the wall. Who joins your camp currently? Halsin and Volo and now Barcus. Who can you actually ask to join your party even though they turn you down? Karlach, Halsin and Barcus; though Halsin and Barcus join your camp. Volo just kind of invites himself, really, but if he's at your camp, it makes sense that he'll likely be playable as a party member.
So yes, I'm assuming, but it is based on some pretty big signs. I mean, why have all these people at your camp if you can't have them join you in the party? Withers might even be a playable character, though he's probably not since story-wise he's OP and just there for resurrection purposes. Granted, Halsin and Volo could be the same, but at least Halsin doesn't seem like it.
Anyway, I'm hoping for at least Halsin and Karlach.
