"The smart phone app that we’re creating, that will be part of our online service, we believe is going to be a very compelling part of the overall proposition because that’s how you’ll voice chat, that’s how you’ll do your matchmaking, and create your lobby. We also think it’s a very elegant solution because if you’ve taken your switch on the go, you’ve put yourself in a hotspot, you’re looking at get a quick match of Mario Kart in, to whip out some sort of bulky, gamer headset is a bit of a challenge.
So we think we’ve got an elegant solution. That’s a very specific answer to your question." - Reggie.
"The important takeaway from this interview is the apparent fact that all of your typical online interactions will be facilitated by the application." -
