Here's something that could be exciting but also could be a whole lot of nothing. So keep expectations firmly in check, but work submitted for Linux kernel 6.6 show something interesting from Valve. Potentially a Steam Deck refresh or their new VR headset perhaps?
Someone in the comments of that article made a note about having a "Steam Brick" that would be a steam deck like console.
I've been investing a lot of time into ChimeraOS and Bazzite for universal Blue lately. I highly recommend building a small form factor PC in something like a fractal ridge with an old 5700XT (or the cheapest AMD RDNA GPU you can find really) and give it a go!
We can all steambox again if we just believe!
