I wouldnt call it over-promising or under-delivering ...
I would call it realizing their misstake, and changing their design acording to what people ARE actively asking for at their feedback forum. :P
The intention to add protagonist full VO is the only way I can see current design making sense. Choices are few, lines we get a bland, and devoided of personality, cinematics are awkward with our protagonist's blank stare. Add VO, ala. Dragon Age Inquisition, and things start clicking into place. Full VO protagonist is not what I ideally want, but I feel it would be best for the game as is.
