>>42159401For what it's worth, in the GameInformer interview feature. Ohmori said that every new gen they consider a new battle system, in Gen 8 he said they were heavily considering it but ultimately decided that the first console Pokemon should be a traditional take on it, with wilder ideas maybe better reserved for future gens.
He went on to clarify that they've made multiple prototypes in the last years for different battle systems, and that we might see them used in spin offs and in other ways to "test" fan reaction to them (IMO it is likely that Pokemon Quest is based on one of those prototypes) because changing the battle system is something they would like to maybe do, but also aknowledge it has a high risk of pissing off alot of fans.
