Yeah I'd be shocked if the ants were exclusive to pro, it'd make sense that they were much more detailed though.There's no reason why it would be exclusive to the Pro. It will be there on the PS4 but it won't look quite as detailed until you're very close up. Obviously 4K will allow for that detail to be seen a little further away.
Also another guy says he's confirmed that if you leave loot for a while there's a chance other machines will come and pick it up. That's fudgy awesome
