Yeah, that's a possibility too. I imagine it would be easy to port but I never bought it, so I'm not sure how the touch screen and dual screen elements worked.Maybe a Detective Pikachu game for the switch too? I haven't played the 3ds version but maybe they can do a good game with the title for the switch?
They might talk a bit about non-main series game things like events and cards, side games etc. But I think the main chunk is definitely going to be showing us Gen 8.
