Regarding polish and new graphics, that is happening in stages. By the time the game goes gold, there should be no temporary placeholder graphics left. One of the devs expressed it as, none of the art assets from Alpha 1 will remain in the game.

Currently we have some areas, notably the player characters, that haven’t been worked on yet and are dragging down the visual quality overall. The devs know this, and are actively working on overhauling those characters.
