USUM has a giant thick cloud and screenshots of a background with Z-crystal monitors on the walls, a stage and a crowd. Also some sort of gym facility despite the fact that trials are confirmed to be maingame and there's only one building that vaguely looks like a gym.
I know you want to hate these games, and that's fine, I can't tell you what to like, but evidence is pointing towards us getting at least something new in terms of facilities. The quality of whatever we get remains to be seen, it could be shit, but it's very unlikely that we're just getting the tree and the Battle Royal dome again.
