Nintendo released this preview trailer this morning. Though they officially confirmed that they were working on a new console way back in March of 2015, this is the first glimpse they’ve actually released.
As rumored, the system appears to be something of a home console/portable console hybrid. You’ve got a controller that connects to your TV for home use — but slide off the controller’s sides and attach it to the portable display (which also appears to act as the console’s brain), and you’re playing the same title on the go.
Nintendo has been saying for a while that they expected their next console to ship in March 2017, and the end of this video confirms they’re still on track for that timeframe.
