I'd love to hear fully voiced protag, right now it's a little too un-immersive for me to see everybody talk and gesticulate except for PC (it's my biggest worry that if I choose a pre-gen character he/she won't be as much fun to observe as he/she is when he/she is a companion). But it would be nice if there would be an option to turn it off.
I think we could both get what we want if they gave us the option to have a silent protagonist. Of course this would have to mean that characters actually say what is written in the dialogue options and not just some vaguely similar thing.
Personally I'm also interested in playing origin characters and them being fully voice-acted would not bother me at all, because they are their own persons, but if I'm the one creating the character, having a voice inserted into my creation just ruins it all. That's why silence is preferable in my case.
