The new X800M2 supports 4K Ultra HD playback, HDR10, Dolby Vision and Hybrid Log Gamma (HLG) in addition to 4K upscaling. Like the original, the player supports Hi-Res Audio and DSD as well as SACD/DVD-A. The Sony will also support 4K streaming services such as Netflix and YouTube, though it's unclear if it also supports HDR streaming. Unlike the X1000, the X800M2 offers digital outputs only.

Pricing and availability is yet to be announced.
