Lets get real about the most likely scenario with NS.

Why are people expecting Japan devs to support the Switch but not the PS4?

Because the PS4 is not mobile and Japanese gamers like to game on the go.

That's why Yokai Watch, Monster Hunter, Dragon Quest, Professor Layton and Kingdom Hearts were all on the 3DS. That's why Square Enix announced that Dragon Quest XI was coming to the NX (and now that we've seen the graphical capabilities of the Switch we know that it will be the PS4 version).

If everything goes to plan the Nintendo Switch can have an incredibly attractive line-up for Japanese gamers:

- Mario Kart: Switch (enhanced port of Mario Kart 8)

- Splatoon (enhanced port, but now mobile! The Japanese gamers will eat this up!)

- Super Mario Switch (just look at how good Super Mario 3D Land sold in Japan)

- The Legend of Zelda: Breath of the Wild (Zelda isn't the most popular franchise in Japan, but this will likely be released first on the Switch)

- Dragon Quest XI (the PS4 version, likely of inferior quality, but still decent enough.)

 

And these are just the games we know of now, the following games are very likely to come to the Switch eventually as well:

- A new Monster Hunter (the first to be built from the ground up with HD graphics in mind)

- Animal Crossing (this is a no-brainer, Animal Crossing is huge in Japan)

- Tomodachi Life sequel (also very likely, this is popular in Japan and Europe)

- Fire Emblem (another no-brainer and the franchise continues to grow. There's also a Fire Emblem game coming for smartphones which will likely boost the franchise even higher. Just look at the boost old Pokémon games got from Pokémon Go.)

- Pokémon (Gamefreak already confirmed they will be developing games for the NX)

- A new 2D Mario (this is again a no-brainer)

- A new Yokai Watch (Level-5 was on the partners list for the NX. The series is still very popular over there.)

- Super Smash Bros. (and now with characters from Splatoon and perhaps even Yokai Watch!)

I really don't see how the PS4 will be able to compete with a line-up like that.
