We are talking around 5 million for 2017, which would be a 1 million more than 3DS shipped in its first year. Switch is poised to do better than the 3DS as long as Nintendo can ship 4.5 million or more to Japan for 2017.
I think that by the end of the year Splatoon 2 will have above 80% attach rate on the Switch so if there is 5 million Switches sold in Japan - Splatoon 2 will be above 4 million. I expect Splatoon 2 to be bundled for the summer vacation but after that for Nintendo to release limited time bundles for other games. This will make new Switch owners pay for two/three games instead of one at purchase. Themed limited time bundles for MHXX, DQXI, Super Mario Odyssey and other launch year games like Arms, MK8D, BotW etc. New owners would have to purchase a bundle with Splatoon 2 on top of it and I think the 3rd game majority of new owners will be buy will be Minecraft.
This is entirely based on what we saw from Nintendo on the Wii U, since the launch of SMM Nintendo was pushing SMM bundle. They sold a million of that game on the Wii U precisely because that was the only way to purchase Splatoon. Virtually every week we'd see Splatoon aligned with Wii U sales, until I believe Feb 2016 when the Splatoon Wii U bundle was launched(at the highest price for a Wii U bundle since the Wii U launch).
The only game in a similar situation is Minecraft which we've seen mirror HW sales on two devices in Japan - Vita and Wii U - hence Minecraft would be one of the main beneficiaries of the new system in Japan. It was an extremely smart move for Microsoft to have MC ready so soon on the Switch. I think there should be no doubt that Minecraft will end up as one of the best selling games on the Switch as well. Potentially it could be the first Western game to have over 4 million sales in Japan on a single platform.
Sorry wasn't anything personal but you did state in that post strongly though Zelda would have no chance to sell more than a million. I still think 1.5 million for Zelda in 2017 is doable. Zelda sales have not considerably slowed down and 1 in 4 or 1 in 6 attach rate on the Switch for the rest of 2017 is entirely possible. If Switch sales are around 5 million for 2017 that would mean that:
- 1 in 4 attach rate would mean around 1 million additional sales for Zelda leading to 1.5 million copies of BotW sold.
- 1 in 6 attach rate would lead to around 666K more sales which would lead to 1.16 million sales on the Switch alone
While there is also a Wii U verision that currently sits at 100K
You prediction for
[NSW + WIU]Zelda was 620K in order for you to be closer [NSW + WIU]Zelda needs to finish under 1.1 million for the year which means that less than 16% attach rate for 2017.
