Quote from (HP)no, all these assets are from the game, i'm almost certain of it, they wouldn't waste resources and time making complex models just for screenshots. I mean the carefully way they present it and render the image...
Except for the Dark Knight render? It seems reasonable that it would just be a high poly render, the detail would be ridiculous otherwise!
It's not that those other shots of the Dark Knight are bad but it seems to have less detail.
I agree with those other shots though, definitely seems to be ingame albeit promotional stuff...
