Hmm, I would be surprised if they are added more voice sets - the sheer volume of voiced lines if they really are going to make all cinematics voiced is huge - and I think they are still counting on us falling in love with their pregenerated characters. Since you can play as origin characters they have all the dialog options that your custom character has which would put us at 9 full voiced sets and that doesn't include later characters that still can take over conversations. In short, this is going to be one of the most massive efforts in game history when it comes to voiceover, probably along the lines if not even surpassing SWTOR, without being a endless live service to bring in the cash.
I'm also certain we ain't going to see the full voiced main protagonist until very late to reduce voice over corrections.
This on the other hand makes the voices a bit dispointing as for me both sets of male and female voices sound too similar. On top of that it makes me resent the origin characters even more for once again character customization was sacrificed to diverge resources to them.
