Nvidia Shield TV Pro got leaked in an Amazon listing which has since been removed. This will be the successor of the old Shield TV which was launched in 2015.
NVIDIA SHIELD TV PRO LEAKED!

Nvidia Sheild is probably one of the best Android devices available as of now. It can stream content, emulate old school games and can also stream games from the Geforce Now Cloud services.
The device was codenamed as “mdarcy.” Powered by the NVIDIA Tegra X1+ chip, it claims to be 25% faster than previous generations and is found in the new Nintendo Switch. The SHIELD TV Pro also has AI-enhanced upscaling to go from HD to 4K which is possible due to the new chip.

The Dolby Vision HDR, which is a step above HDR10 is present on the new Sheild. The special thing about Dolby Vision HDR is dynamic metadata. This metadata is essentially instructions for the TV display to make sure every scene is portrayed as accurately as possible. HDR10 only has static metadata, which covers the entire movie/TV show.
The Shield TV Pro has a brand new remote. There is a microphone for voice controls, motion-activated backlit buttons, an IR blaster for controlling TVs, Bluetooth, and a lost remote feature. It has buttons for power, menu, play, record, pause, forward, reverse, volume, voice commands, and direction pad.

The device has 2 USB 3.0 ports, HDMI 2.0 port, and a Gigabit Ethernet port. Other specifications include 4GB of RAM, 16GB of storage.
The Shield TV Pro is scheduled to launch on October 28th on Amazon at the starting price of $199. It is heartwarming to see that NVIDIA is still updating and paying attention to this device that is loved by many.
