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.
Honestly all I want is a Steam Deck Mini. Fuck bigger and more powerful, I want a small indie/AA game machine that's easier to carry around and use as a handheld outside of the house. The Steam Deck has been primarily a bed machine for me.
