The device will not be first portable PC gaming device with removable controllers; the crowd-funded OneXplayer apparently gets that crown, but this one mimics the Switch Joy-cons’ ability to slide smoothly off from the main screen of the system for detached play.

The slide-off controls mean you don't need to purchase or drag out a separate controller when docking the device to a TV or monitor. And completely detachable controls for each hand means you can keep your hands as far apart as you want while you hold each "half-controller" separately.

The Legion Go also sports an 8-inch diagonal screen, which is 1 inch larger than Valve's and ROG's devices.

All this is being leaked after Lenovo abandoned its button- and cooler-packed Legion line of Android-based gaming phones as part of what it said was a "gaming portfolio consolidation."

The Windows 11-based Legion Go — which Windows Central says will be based on AMD's Phoenix processors — should have the high-end PC gaming support that the Legion phones lacked.

Windows Report believes Lenovo "is preparing to launch an entire gaming ecosystem alongside the Legion Go" with a new pair of Legion AR glasses specifically tweaked for gaming."
