Valve won't be releasing a Steam Deck with more performance until at least 2025. Given the smartphone market's reputation for disappointing incremental updates, this is the right choice. Valve should, however, throw gamers a bone with a Steam Deck 1.5.
Except Valve said they don’t want a mid-gen refresh. They want game developers to have a fixed target for performance optimalisation.
A mid gen refresh wouldn’t change the performance target, just offer a better screen or something like that.
