To be honest, Nintendo could do some neat marketing with this. Have some dude climbing a mountain, and when he reaches the peak, the familiar screech of a dragon fills the air. A shadow swoops over him, he raises the Joycons like he's dual wielding, and then shift into gameplay. Eventually pull out again to show him playing on the Switch, before saving, turning off, and heading back down. Take the adventure with you on Nintendo Switch, etc.
Still, should be interesting come January. Skyrim seems like one of the big pulls for the system, and if anything could prove the viability of third party software on the Switch, it'd be that.
