No we wont, its no longer paying off to invest that much.
Write a bunch of new shaders - nobody notices anything.
Write a good procedural content generator- suddenly applause.
The gfx-race is over- it died a horrible death on the plateau beneath uncanny valley. Its a real shame, cause the technology invented is just so neat- but that is how it is.
Battlefront just won a ton of awards due to tech they created for that game that makes the terrain look amazingly realistic. It seems like people still notice.
I didn't say for everything and in all cases, but there are cases where you can't tell. GTA V and Battlefront both can produce screenshots with tons of detail (including foliage) that are near imperceptible from reality.
Where games struggle today is hair, skin, and soft fabrics, but there are already good implementations for those that should show up in the next generation game engines.
This will always been an iterative process, but there are times today (and I honestly feel like this just became the case within the past year or so) where games look like reality.
