Edit: checked the one you said, i am guessing there is a mistake with that one, it looks like a 360/ps3 version to me. other pics dont show that big of a different, it just cant be right.
That's what i thought too. The PS4 version looks quite obviously better, but the 7th X1 screenshot looks way too blurry. The HUD is clearer in some of it's other shots so its either a shitty screenshot or (more likely looking at the lower detail in the distance) a PS3/360 version.
