I was sitting here thinking and reading about the potential of Pokemon Stars coming to the Nintendo Switch. Then it dawned on me, you have never been able to catch all of the Pokemon in any one version of the game. If Stars is the only Pokemon game to come to the Switch it will mean one of two things. This is the first version in which every pokemon can be caught, or more likely there must be some kind of trading between the Switch and DS.
