It's obviously not done yet, seeing as how they don't have wall mats, signage, etc. and there are literally boxes of equipment in plastic wrap all over. I think they put the mats down to show a reference for how massive the wrestling area is, and yeah, it's huge. As for it looking dark and gloomy, well, their color scheme is black with a tiny little bit of yellow, and I'm sure there are going to be some lighting updates as well. I think new mats have a powdery substance on them to keep them from being sticky, not unlike how new machinery has oil all over it that has to be wiped off when it comes out. Bottom line, this is going to be the biggest and best facility.
