From what I've seen,it will be close to the original, except you *might see action icons on objects you can interact with. (There's no knowing whether this will make it into the final build and stay after the following updates)
Personally, I think there should be some tweaks to it if they plan on keeping the icons.
I don't think objects you can mantle over need to have icons indicating you can do it. Bf3 did fine without it.
Doors should probably just be retextured in a way that makes them easy to tell they're breachable. (I don't have any ideas,but in Rainbow Six Siege made all door barricades have an X spraypainted uniformly on each and every one of them. You can instantly recognize them after your first playthrough. A uniform design of some sort wouldn't be so bad. )
On dropped weapons having the icon (that indicates you can pick them up), I think the icon should only appear a few seconds after the former owner is killed,and should only appear if you down look directly at the weapon and have only a few mags left.
