I agree, mostly, except I'm a little skeptical on the Umbridge ones. I could see it happening in fanfic and I'd probably believe it, but I don't know if JKR will do it.It's just something about her exit in OotP that makes me think Umbridge won't be showing up for the third act, but you never know. I think it'd be cool, anyway. It's nice having a villain you can really imagine meeting in real life, rather than one that looks like a snake or sounds like Darth Vader or whatever. (Not that there's anything *wrong* with that type, but Umbridge-type ones are easier to hate.)
