It looks like they're doing away with the gyms and replacing them with the Trials, which actually breathes life into a tried and true formula. After twenty years of "Defeat 8 gyms and then the elite four and then defeat an evil team along the way", it's actually cool that they're trying something new. Also, someone compared the Z-moves to Limit breaks in Final Fantasy? As long as it's balanced well, I don't think power creep will be much of an issue. Also, it seems as though JoJo is leaking into another franchise.
