Could switch beat 3ds? 3ds's 300 to 400k next week's seems to much for the poor switch.
Those weeks will definitely be tough to keep up with, especially under constant supply constrains. But I think Nintendo has now worked out their supply chain and will be able to ship more and more units to the different parts of the world for the holiday season, so it might get closer to these numbers than one could think just a couple of weeks ago.
