I'd love to believe this is real, but I've learned over time to never trust this this stuff or else I'll just be setting myself up for disappointment. I'm team fake. Even if the video is convincing, it's frankly just too good to be true. This is basically just the wishlist of all the features that we all could ever want crammed into a single update. If we ever get any of these features, they will be drip-fed to us over the course of many years, and probably implemented in bizarre ways. Nintendo's great at making games, and occasionally have a cool idea or two for their new hardware, but I don't expect much more of them when it comes to these kinds of features.
Also, I don't see any proof of a "Virtual Console" in this video. The guy just appeared to create a custom folder with "Virtual Console" in the title.
