Zotac did have Zbox's with Raven Ridge in them at CES, though:

Besides the consumer Raven Ridge CPUs there are also 2 OEM 35w versions that are downclocked slightly while shaving off a huge chunk of TDP. They are named like 2400G but with an E on the end, ie 2400GE. I imagine if AMD really wanted to put the effort into a 15W chip they could manage a ~2.5ghz quad core with Ryzen modules.

Honestly curious: why get a ~$1300 Linux console over say a Nintendo Switch or regular PC? Seems to me SteamOS was a great idea but is dying? Anything I am missing, any killer apps/games?

It's a very fast, general-purpose computer; 1070 also can be used for crypto-mining, so when you aren't playing, it can run ETH/XMR/etc. mining and as it's pretty low power, you might even be profitable. Deep Learning model training can be done too if you have such a need as well. I bought it as I wanted to help SteamOS not to die and bought all AAA titles that were available on SteamOS.
