The problem with having an SKU without a gamepad is that it would have removed one of the biggest features they were pushing for, and it might have divided developers since the gamepad couldn't be assumed. With Switch however, I could definitely see them doing dockless version with the Joy-Cons built-in, depending on how reception ends up being with games that utilize the multiplayer aspect of Joy-Cons. It's weird because the Switch can easily replace their home console divison, but 3DS is still successful and selling right now so there's no telling if they'll end up tuning the Switch more to one side or the other later on.
