NX reveal imminent! What Nintendo needs to do to slay during the reveal?

[Darwinianevolution]

-What the NX is. And explain it WELL. We can't have another WiiU situation. This is ESENTIAL for them.
-Show the games. They exist, so why not a trailer. Maybe some 3rd party too.
-They don't need to show specs, but they do need to tell us after the show. Price would be great too.
