I didn't think any elf voice made sense, aside from the altmer. But even their voice could do with a change. Fortunately for everyone their statement about have lots of voice actors gives promise to having many different distinct voices. We shouldn't have the oblivion problem,
I hope so, but if you want 3 different voices for each gender and race that's 60 actors just there (unless there's some doubling) - but let's hope they stay true to their word.
Edit: On topic, I voted to bring 'em back from Morrowind, or rather its style, but yeah, I'd like for some diversity as well.
