This is the first time they played this live with a controller. (Btw you can carry over your smartphone game data to the Switch version of the game.)
...They're doing this to hide the fact that there's no cartridge in the retail version. Meaning with a user-printed sleeve they can conceal that disclaimer they're required to put on the top of the box.
And an upgrade to the game's icon.
Weird they announce that long after the launch of the game on other platforms.
