This is what he said :
instead of having some sort of bulky gamer headset, you’ll be able to do it right off your smartphone, put in your earbuds that you use for your standard mobile device. We think that’s a pretty sweet solution. That’s part of the overall opportunity that we see in a subscription service.
Why would we pay to use Nintendo's voice chat app on smartphone when we can use Skype, Discord ?
What about people who doesn't have smartphone? What's the point of paid online service If we don't have it directly on the Switch?
I think the nightmare of the Switch will never end, I have no words to explain my disappointment.
