Looks like this is (likely) getting delayed to 2020 - but for the best reasons. According to a tweet by Yu, there is just a ton of stuff in the game to make sure it’s ready before it goes live.

He goes on to mention that he took early criticism of the art to heart and has worked on improving it, though he mentions some of the issue was seeing the game in compressed videos, and I personally dug (har) the way it looked before, I have to admit this is a marked improvement. I grabbed the image he presented (on the right) and put it next to a screen grab (taken from YouTube, so it’s not a totally fair compare) from the PS4 trailer to show off the same environment. You can see lots and lots of new details in everything from the chain blocks to the walls themselves.
So, a delay, but for the best of reasons. Take your time, I say.
