I'd trade a voiced main character for a non-voiced one if it gave players the option of multiple races even if was just a purely cosmetic thing. Full disclosure, I played as a human in DA:O, but like was said earlier I somehow found myself connecting better to my mute character in DA:O than the voiced Hawke in DA:2. If they would just get rid of the wheel it would be fucking great because, by its design, it's too binary. I'd actually love to see a Bioware game without a Paragon/Renegade mechanic. Just give me a list of dialogue options and let me role play. It's much more fun and personal that way compared to the wheel. The wheel basically boils down to boy scout, neutral or dick. The problem with the mechanic, as is the case with TOR, too much influence is placed on the bonuses. You can't really feel like you can play as a nuanced character because you need to fill up your light side/paragon or darkside/renegade bar. DA:O had more of like a KOTOR-style influence system. The dialogue options were more organic.
I'm willing to give DA3 a shot since I loved DA:O, but honestly I'm more worried about the corner they painted themselves into with the mage/templar conflict they established with DA2. With DA:O, the characters seemed more three dimensional. In DA2 they were like cardboard cutouts. It didn't help that every mage in DA2 whined about being persecuted because people were afraid of blood mages, yet every mage turned out to be a blood mage. The templars were just as dumb. If DA2 story logic applied to DA:O my party camp wouldn't have survived a night, Alistair would have been a facist and Morrigan would have been slitting her wrists every three seconds to summon a demon to kill everyone.
