Very good numbers. The Switch will overtake the GC soon enough. As for the software, they will keep growing but very good numbers already. BotW will be the most successful Zelda title, MO will probably go over 15m this year. I also am really happy with Xenoblade 2's numbers. Highest selling Xenoblade title and it shows that the franchise is growing.
Nintendo 3DS vs Switch hardware shipments / LTD sales comparison:
3DS Q1 2011: 3.61 million / 3.61 million (Feb/Mar launch)
Switch Q1 2017: 2.74 million / 2.74 million (March launch)
I was wondering how the Switch did in comparison to the 3DS. Sweet! It managed to surpass it and have a stronger first fiscal year! Seeing as how the Switch is outselling it weekly (weeks aligned) and is still priced at its launch point of $300, these are some encouraging signs as to how high the Switch's ceiling is.
