Persona 6 could have a good idea on its hands by revitalizing one of the lesser-appreciated mechanics of Persona 5 Royal. The Persona games have established a lot of mechanics over the years, and Persona 6 is pretty likely to follow the same general approach. Even beyond that, though, there are a lot of good ideas that could benefit from a second look. Something that wasn't especially noticeable before could get turned into a highly useful feature in the next game, and Persona 6 could be due for a big, yet unexpected upgrade with an unorthodox approach to weather.
