How do you think Gen 9 will deal with battle gimmicks?

a) remove the already existing gimmicks and introduce a new one (like SwSh did)
b) remove all gimmicks and don't introduce a new one (like BDSP did)
c) bring back all existing gimmicks and expand on them (new megas, new z-moves, new gmax) instead of creating a new gimmick
d) bring back all existing gimmicks and introduce a new one, somehow balancing the game around four different gimmicks
