Valve will loose competition quick if they wait that long. Asus is probably already working on a rog ally 2, legion go came out and is packed with features. Aleast release a steam deck with the newest GPU, ram and a 1080P 120hz or 144hz oled or QHD 500 nit screen within a year or so from now.
Dude, the newest “GPU” is the one in both the Ally and Legion Go. It’s incremental at best (at 15w). There’s no point in a SD2 when the most important thing hasn’t made substantial improvements yet.
Basically, we’re waiting on AMD.
Say what you want about consoles but it’s nice knowing it’ll get support for at least 5 years.
