Actually I find it's quite amusing that people think that Switch has problem in Japan, we talking about $300 device that still has launch price point and still not single one revision and despite that Switch has very strong sales in any case. For comparision, 3DS (that sold incredible strong in Japan, and was 3rd best selling handheld/home console ever) in same time period already had huge ass price cut and one revision, also worth mentioning that Switch was selling better in same time period than 3DS until 3DS didn't receive huge price cut.
Switch sales are strong in Japan, but Switch sales will really explode in Japan when Switch gets to around $200 price point and when people start buying it like device per person.
Exactly, what Tak13 hasn't fully factored in is what would happen when price cuts finally bring the Switch nearer to HandHeld price points. This is the first Hybrid and its sales curve is very likely to exhibit some unusual behaviours.
He is right though in saying the Switch at present doesn't look like it would be close to the 3DS in sales but that also should be expected to some extent. Right now, majority of people aren't buying it as a per person device in Japan.......and even in most of the West. I think the Switch still has quite a few surprises in store for many sales observers.
The main thing for Nintendo is their answer to the question, when does the Switch get its Price Cut to get that fine balance between Revenue and acceleration in Sales when it just about starts to slow down.
