Bethesda say they have improved 3rd person mode... which can only realistically mean over the shoulder GOW style. Considering the trend in most 3rd person games.
Or it could mean that... they improved the 3rd person camera. The third person screenshots (obviously not necessarily a good indicator, since they could put the camera anywhere in those) don't make it look like it's going to employ an over-the-shoulder view, and over-the-shoulder is still only a trend for shooters - most third person games don't use it.
I predict a cover system too.
That makes literally no sense.
