Also, is it an application on the switch or is it for developers? I highly doubt it is for developers because of the depth they have to get into for programming the Switch. And you have to be a game developer to receive a switch devkit, so I wouldn't plan on coding anything for the switch until either the dev program opens it up or it gets onto the eshop. And they already know what happened last time they used a sandbox programming tool on a console (SmileBASIC)
