I only see 9 weeks of HW data for NS. How do you see 3 months?
WiiU was unprecedented:
2012 + 2013: 5.3M
It would only require this for NS:
But let me know your prediction. It's easy to "counter-bet", not so easy to bet.
I am extrapolating month 3 sales based on month 2 sales and the knowledge that Switch is still selling through its stock quickly. There's no good reason to assume that month 3 sales will be notably lower than month 2 sales. But even ignoring that. VGC has been showing weekly sales of ~200k after the launch month. Wii U had weekly sales of ~40k. That's a huge gap.
Your Wii U breakdown combines 2012 and 2013 for a period of 14 months that includes two holiday seasons. This skews the numbers and is not an accurate or honest representation of how Wii U performed.
My prediction for Switch lifetime sales is more than 100m units. I am obviously factoring in that Switch is the successor to both the Wii U and 3DS and that's the most blatant mistake in your prediction. You are aware that your prediction will be very wrong if Switch is also replacing the 3DS.
My signature contains the link to one of my threads, but I post it for convenience because many members have disabled signatures in their VGC settings.
The thread was created shortly after the Switch presentation in January and calls out all predictions of 50m or less. This means that I was and am so confident in Switch that I consider anything below 60m ridiculous.
