I'm holding out on that one until I see it work. AI voices have certainly reached the point where I don't mind listening to them for a good period of time, and they can match the basic contours of someone's voice, but at the moment they are still missing precisely the fine details a game needs from a voice actor. And I don't know if this is just a matter of a few last tweaks or if it's a case of the last 10% taking 90% of the work. I'm not saying it's impossible, just that I'm waiting until I see it before I declare that it's here.
Personally I've nearly entirely bowed out of AAA gaming. The harder they push the graphics the more everything else ends up trashed. It isn't even a lack of effort per se. It's just that if literally everything has to have pristine animations and perfect voice acting and physics-based interactions with its environments, you get less than when all you needed was a 5 frame pixel animation and a funny sound effect for some particular interaction. AI can only cut into the problem there but not solve it until it is essentially not only human-capable, but human-capable in realtime, which is literally getting to holodeck levels of computation.
