Yeah, even that is a weird take. Like I guess Gen 7 was kind of innovative (but honestly I think the difference between trials and gyms was a bit oversold). Sword and Shield are innovative in the sense that they're finally taking steps to modernize aspects of the series that should have been done on 3DS, but I would not call that particularly innovative. The only real big "innovative" change was overworld encounters, and BDSP still has those in the underground.
I guess maybe they could be referring to Let's Go, but "innovative" is not the word I'd use for anything in that game.
