The Rosti clarification sure sounds like he's confirming it. He calls it a "leak", he says that people (I'm assuming Nintendo people) are upset about it, and references/compares it to leaks that happened earlier this year. Sounds like he personally doesn't know what it is but that people in-the-know aren't happy.
Remember the NX survey leak? I know that people in the know where upset about it because it does not represent NX, but people mistook it for being actual NX info. It is not upset about a leak, it is upset about wrong info getting spread.
Isn't this device supposed to be android based and potentially use mobile processors like the snapdragon 820 plus coprocessor?
Just saying it might be real.
No, no and no.
