Reddit user Silencerr put together the above video as a tour of sorts of the new raid zone. Because this is just datamined files, it likely won't look exactly like this on live servers -- the lighting isn't present, and any filler doodads, mobs, or bosses are absent. Basically, it's the sandbox version of what the raid will look like -- and anything can change between the PTR and now.
However, the video is actually pretty neat. It's dark, it's gloomy, and the broken halls are frankly kind of disturbing. It almost reminds me of those creepy crypts underneath Karazhan, although there are no Upside-down Sinners floating around. More importantly, this raid appears to be massive, and definitely on the scale of zones like Black Temple or Ulduar. It's huge, it's menacing, and I can't wait to see what it looks like fully-realized and implemented in game.
