People have poor memories.
Both playstation and xbox wanted their latest consoles to be digital only. Do you not remember the huge huge backlash of the reveal of the xbox one and digital only? Less remembered is how Sony was taking the exact same position, but they backed off when everyone vowed to not buy an xbox until microsoft reversed their decision.
Of course they want digital only. It is only positives for them. Complete control over sales and distribution, complete ability to track ALL numbers, less overhead, less materials, more control over the rights of ownership (physical owners have more legal rights to use software than digital owners), among other things. The *only* reason they don't do it now is because of potential backlash. Digital is great for these companies, whereas physical is far better for the consumers' rights. Expect them to keep trying to turn everything all-digital, and expect people to keep fighting this.
Nintendo...well, they tend to be a bit more consumer friendly. So they'll probably keep trying to do physical for as long as it makes sense. With bigger and bigger sizes for games, who knows how long this will be possible.
