I am on that side that believes SD2 is actually pretty far away like 4-6 years from release. Valve achieved what they wanted now - a device that’s very compelling to buy that makes you a game hoarder also. The project to feed into the main business model is there and it works.
When it becomes obsolete and there are fairly significant advances in tech, then I think news can be on the horizon about the SD2. This is all my assumption
My LCD has them tight and nice and OLED has them loose like they’re bought from a Bazar shop…
