I don’t think it’ll be for a while, as not only do a lot of people still purchase most of their games physically, but Nintendo was really on the “we sell packaged goods” train until recently. That said, I think they’re going to get more and more aggressive with their coaxing of the audience towards digital, through the gold points program, the voucher program, etc. Digital makes more sense for them as a company because it’s immensely more profitable, as it costs much less to send a few GBs of data over the internet than it does to print a cartridge, box it up and ship it to stores. They also get more control over access: digital games can’t break street date, which is very important to them. Lastly, as was alluded to by Phil Spencer in that Kinda Funny interview: a carry-forward digital library is a great way to generate platform loyalty and maintain a more permanent relationship with the customer. Xbox lost the Xbox One/PS4 generation, and as Phil said, that was the worst generation to lose because that’s when people started building their permanent digital library, which was one of the factors in a lot of people’s next gen console buying decision. A lot more people will be tempted to buy a Switch 2 if all of their digital Switch 1 games are right there waiting for them, with some of them running better than ever on the new console.
I don’t think it’s going to be an overnight flipping of the all-digital switch, either. It’s going to be a gradual wind-down, which I think you’re already seeing in some ways. More codes-in-boxes, shrinking retail presence with fewer shelves of game boxes and more pegs of register-activated code cards, more day-one digital shadowdrops with physical releases being a few weeks later, smaller print runs, etc.
But yeah, I definitely don’t think Switch 2 will be the forced all-digital console, nor do I really think it’ll be Switch 3, but I’d be shocked if there’s the big Walmart glass-encased shelf of Switch 3 games. Maybe a smaller cabinet, like the one they keep SD cards and hard drives in. But there’s absolutely going to be a huge wall of pegs with register-activated code cards for games to give as gifts.
