I would get pretty frustrated if I had to sit through that at the beginning of every round. I like how they switched it to a cinematic you can skip.
I like the skippable cinematic too.
If they did go with the chatty AI they could have done it similar to L4D but since at the start of a round everyone rushes off it kinda wouldn't have worked.
Overall: I prefer what we have now thanks.
