So according to journalists, the game is 720p, skips frames especially the further something is from you to the point that it's single fps, just like in Arceus engine, and is laggy as all hell, with like 15 second load times when switching in battle and terrastalization, also terrastalization cutscene is not skippable.
Also, the moonwalking in place while rotating thing is still there, only now on the player character every time you enter a building, not just select cutscenes. Speaking of, most buildings are just menus now, and there are still blurry lowres textures on many things in the environment.

And they're almost certainly playing the release version, because it's less than a month from public release, there are already cartridges being minted and they played it directly at HQ. Giving them a buggy version when a better one exists is bad PR for no reason. There may be a day1 optimization patch. I heavily doubt it, that would require basically a full overhaul. Also, fuck offline players I guess. Go drive to your nearest mcdonalds or starbucks and update the game on their piss-poor wifi.

On the plus side, they did all have fun. Gameplay, performance issues aside, is very good. Music is also good.
