I have always bought most of my games at launch regardless of platform, so I would have never known this was an issue until people told me about it. I barely ever see a price tag under 60 USD personally.
Having said that, I think it comes down to when they go on temporary sales on the eshop. For example, a game on PS4 gets a permanent cut and there is still no rush to go out and buy it. A Nintendo game goes on sale on the eshop, and it instantly shoots to the top of the chart. Having the full price at 60 USD makes people feel like they need to grab it when it goes on sale, and a full price cut just doesn't motivate people to move the same way.
