500 million + seller. You heard it here first! Do I get an old VGC vibe?
OT: 120 million. The Switch is selling as successful Nintendo systems usually do. But as soon as Nintendo will push their first-party developers to the S2, sales will drop considerably. Still, IMO it will be the most successfull Nintendo system revenue wise, easily surpassing the DS by quite a margin.
