I don't think they'll be adding any new characters soon, since some of the characters don't have their story fully completed, and Richard's story has just about begun. But I am looking forward to a story with Ted, and maybe the cop bear, but I don't think that might happen, but due to spoiler reasons I can't say why. And I also agree with you on the Harold story, I really enjoyed it and had me in a mix of emotions a lot of the time, since it was a rocky story, I really hope that more people support this VN and it's creator!
