Looks like someone over at Amazon drank one cup of java too many....
Someone got their Christmas wish, since it now includes Dolby Vision. Specs get a bit of a bump with the Tegra X1+ processor, BT 5.0, and a new remote to boot.
Supposed to release on Oct 28th according to the Amazon listing at $199 USD. Hopefully we won't have to wait a few years for it....
