See, I'm conflicted with this question. I do feel that with the way that GameFreak creates/presents the current games, we have too many for them to all be in one map/game. BUT, if GameFreak in the future begins to expand outside of the stereotypical game, and create more open-world, challenging concepts, I think the number could be infinite. Implementing the idea of seasonal Pokemon like Animal Crossing does with their animals, getting away from the extremely easy "hold your hand" concept and adding challenge that both kids and adults can enjoy, creating maps that are much more extensive so that you can access specific Pokemon only in very specific places (and making them actually rare).
I think GameFreak recognizes that they could make a MONSTER of a game, but for whatever reason, they choose not to (though, Pokemon Legends may be correcting that). Back to the topic at hand, I don't think there will ever be "too many" mons, as long as the games are capable of keeping the player entertained with the number and not just doing the same thing over and over again.
