We've already caught two official looks of the Nintendo Switch thus far, with the console shown off in a reveal trailer, as well as a spot on the Jimmy Fallon's Tonight Show. Those have been detail light though and have only really sold the concept of the console, not the functionality or the games we can expect on it.
A full look was promised in the new year, and we finally have a date for that. On January 12 at 8 PM PST / 11 PM EST, Nintendo will host a stream that will last 45 minutes showing off the console in its entirety. That's 4 AM for us UK lot.
It will be good to finally have the console's details out there. Hell, the console is out in March. That really isn't long now.
