Honestly, when I watch those on-line videos I don't see the ghosting only motion-blur, but if you can point us to a time stamp in a particular video from the GIF fragment that you posted I'll certainly have a look.
I sort of feel that the comparison with GOW here is invalid - because the car is moving at 150+km/h and the camera / character is moving at least 1/10th of that, so the motion vectors in GOW are likely to be 10 times shorter, as is visible in your post.
Additionally the QA process internally first, then Namco's QA team and then 1st party's team haven't highlighted any issues around this area. Again, this is a subjective area so unlike the matters of absolute fact here that the render team have engaged in - feedback is really welcome. Motion-blur levels are a product not just of the graphics team, they are balanced by art direction and production team.
