Wii in fiscal year Apr 09-Mar 10 is probably the best comparison.
It kinda just coasted with small-medium tier titles for most of the year and had two big things that pushed sales like crazy during the holidays.
1. Price cut in the last week of Sept.
2. New Super Mario Bros Wii in Nov.
Its similar to Switch this year in that its been coasting with some medium tier titles and is saving two big guns for the holidays, Pokemon & Smash Bros while likely also getting its first value bundles.
Thank you for the data. Do you know where we can find EVERY fiscal Q results for every machines ?
So I still bet that Switch will break the Q3 record of all time and make a 12M. So 20M is still reachable :
Q1 = 1,88
Q2 = 4
Q3 = 12
Q4 = 4
If they make a price cut they can reach 22M+
