If you aren't a fan of the Joy-Con you can use a Nintendo Switch Pro Controller that looks similar to a traditional Xbox or other dual-analog controller.
The tablet connects to a TV via a dock, and can slide out easily when you want to take gaming on the go. "In addition to providing single and multiplayer thrills at home, the Nintendo Switch system also enables gamers to play the same title wherever, whenever and with whomever they choose," Nintendo added. "The mobility of a handheld is now added to the power of a home gaming system to enable unprecedented new video game play styles."
Perhaps most importantly, Nintendo announced major third-party support, includingSquare Enix, Sega, Konami, Activision, Bethesda, Capcom, Take-Two, Warner Bros. and EA. This is a stark contrast to the Wii U which died after game publishers stopped supporting the console.
Check out the trailer below as it explains the system better than I could have:
