>>35200632Why keep making up arbitrary hypotheticals that will never happen? Yes, if they made a brand new adventure in a completely new region with only new starters and no other Pokemon, it would be gen 8.
But they wouldn't do that because it's stupid. No one would buy that game. If they want a new gen they have to add a lot of Pokemon.
If USUM had zero battle compatibility with SM, it would still be the same gen. They don't NEED to keep compatibility though, the same number of people would have bought USUM.
I didn't respond to your other point about by-products because it's the dumbest thing I've read on /vp/ today. Did you even think about what you wrote? They wouldn't arbitrarily cut off compatibility and then say "OK so because of that, now we'll have to make 50 new Pokemon".
