Nintendo Switch Lite Announced, Releases Sept. 20th!
This system is dedicated to handheld play for gamers on the go, so it will not be able to connect to your TV, and you will need extra Joy-Cons to play games like 1-2 Switch. Also since the controllers are built in, they lose the HD Rumble and IR Camera functions. Nintendo also stated that the Lite will have a slightly improved battery life.
It releases on September 20th, for $199.99.

Compact and lightweight
With its light, sleek design, this system is ready to hit the road whenever you are.

Built-in controllers
Controllers are built right into the system for handheld play, and the left side sports a +Control Pad.
