Switch Sales Predictions: Open Your Eyes - UPDATE: Switch LTD Shipments Reach 111.08m by June 30th, Forecast for Current Fiscal Year Remains at 21.0m

I think there's actually a chance that the Switch ends up in between the DS and PS2.
If it ends up at roughly 109mil at the end of this fiscal year and then sells as follows:
FY22 - 21mil
FY23 - 15mil
FY24 - 8mil (successor releases)
FY25 - 3mil
That would be 156mil in the end.

@PAOerfulone, I think you're being a bit to generous with the last few years. Unless the successor is not backwards compatible.
