I wondered this from the start and here it is proven. I don't think they actively want to remove PC footage, more just that it is embarrassing that they tried to make people think it was Xbox footage and it was actually PC footage.
I bet they approximated the Xbox visuals though, they just ran it on a PC to keep the framerate up while they optimize.
