The amount of detail is what i think the game used to be then they dumbed it down for current gen. I also think that the next gen and PC releases will look like the trailers, freeking amazing. As XBO and PS4 both use similar architecture as PC i think when PC comes, so when PC comes expect next gen stuff. And im sure that will be carried over to the consoles too.
What im trying to say is they wouldn't have gone into so much detail, knowing they had to go out lumber jacking. My guess expect delayed PC version to match next gen consoles release date and graphics.
(This may not be the correct location but its the closest I've found.. it also is a good comparison).
