I was thinking of an article I read about Switch vs. PS4 launch sales. It referenced Japan, not global, numbers. The Switch has sold more than 2:1 over the PS4 when you compare their first 6 months on shelves. https://www.forbes.com/sites/olliebarder/2017/09/04/in-japan-the-nintendo-switch-sold-more-in-its-first-6-months-than-the-ps4-did/#5f13085c1d02 Nintendo hasn't released sales totals in a while but had sold over 5 million units as of July (roughly 4 months on the market) and outsold PS4 and Xbox One during 4 of the last 6 months (and that's with the hardware shortages). PS4 had about 8 million units sold in it's first 6 months worldwide but that also included a holiday launch. It will probably be a more fair comparison to look at first-year sales of the two platforms so that we can see what impact a holiday will have on each. Some predictions were that Nintendo could sell up to 18 million units if they have the hardware available for Christmas, but that's probably a bit high. Realistically they'll hit at least 10 before New Year's and beat the Wii U's lifetime sales before spring. EDIT: The Switch also has the 2 highest rated games of the year so far (Zelda: BotW and Mario Kart) and expectations are ridiculously high for Super Mario Odyssey. The Mario bundle will probably produce a surge in sales when it releases late next month.
