If samsung 2nm works out then maybe a qualcomm/nvidia/amd zen 7 device on that would suit valveAs much as I'd like Valve to revamp the hardware, it has a point. Even Z2 Extreme devices like the ROG Xbox Ally X aren't that much faster, and there are considerations like power draw, heat, and cost.
When it does come time, I would like Valve to rethink the design. The Steam Deck is a behemoth, and I'd like the company to shrink it down without eliminating trackpad input or hurting battery life. It's hard to rock a handheld PC when it swallows up most of the free space in a backpack.
