It's basically a more powerful Steam Deck that's connected to a TV. The games will be "verified" and the settings pre-tuned for ideal performance just like the Steam Deck. They did a good job making the most of mediocre hardware in the Deck.

My initial thoughts were that this thing would cost considerably more, but I'm looking at the specs and it might not be too bad. Maybe it'll start at $499 or $599 and go up $749 or $849. I'm guessing SoC and not easily upgraded. It says Zen4 so it won't be Strix Point/Halo, but maybe some bastard variation with a Zen4 core and newer GPU than the Deck.
