I'm glad you guys are moving ahead with this. If I remember rightly a Blue Planet team member said they didn't expect WiH to ever get voice acted, as there was simply too much dialogue, story text etc. While the sheer amount of text must be daunting, it's good to see this may be happening after all.
I read that you guys were aiming for the in-mission dialogue to sound like real soldiers barking orders, and I love that about BP, 'cause I think you achieved it (I know nothing about how realistic this actually was, but to my untrained eye it was entirely convincing). But oh, how immersive it would be to actually hear it being spoken, with a deadpan, non-emotional professional military voice telling you to kill all these Tevs rather than simply reading their orders. It would really make the whole thing even more intense than it is now.
By the way, who voiced the Orestes in AoA? His voice was my personal favourite, I'm not sure why, but I felt he conveyed a lot of subtle emotion with his performance...like he was well-trained and professional but you could always hear a hint of fear/confusion in him...
Excuse my ramblings. Basically my point is, WiH: excellent. WiH with voice acting: perfect. Which I'm sure you're already aware of.
