Wow this sounds incredible! Really hoping Pokémon Company can pull it off... they don't have a great track record during the Switch gen. They'll have had four years to work on this title, longer than any other mainline entry. I'll stay optimistic. An open world Pokémon filled with redesigns and an entirely new engine sounds extremely promising.
