As a reminder, we also have the Nintendo Rep conference starting in a week, which is usually focused on the most important launches of the next 12 months, specifically in regards to messaging, marketing campaigns, and retailer cooperation within North America.
I don't think there's necessarily any guarantee that we'll get a full reveal by the end of next week, but between these two events (EDIT: If this retailer meeting is real and ends up having literally anything to do with NX, which is a bit of a long shot in my mind) I think there's a good chance of somebody slipping up at the very least, though I wouldn't put any money down on it.
And if Emily Rogers thinks there's a 0% chance of a reveal this week, then I'm personally pretty willing to agree with her. No reveal this week also makes me want to step back a bit on the rep conference angle, because I always found a reveal the week of to be less likely than a reveal the week before.
