Nintendo says it has no plans to ditch physical games, knows how much fans like it

While you're absolutely right and I largely agree.
I think there is a couple of important points to caveat here.
- You're right these stores get closed down, but you can still download your games from the old eshop on any of Nintendos closed stores via your purchase history.
- You're not getting all the negatives of Sonys decision, personally I'm indifferent about game key cards, it's not a biggie to me if I need to download it before playing it. (obviously i'd prefer the option of them on the cart). I just need to be able to buy it from another shop, share with friends, swap with buddies, sell them on. I need an open market.
