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?
I think there's a new Steam Deck coming. The old one could really benefit from faster PCIE speeds, among a few of other hardware upgrades.
Unlikely. APUs aren't that much more powerful yet.
My guess would be Deckard (the rumored VR headset) or possibly a new steam machine. Longshot on that one though, I think.
