Valve har allerede slået fast at Steam Deck er succesfuld nok til at de har sat gang i udviklingen af en efterfølger, som dog er adskillige år fra en eventuel lancering. Den kunne desuden have et OLED-panel, men netop den teknologi er Valve ikke helt sikre på.
I et interview med PC Gamer Valves Pierre-Loup Griffais, at de overvejer OLED, men at dette vil blive svært at implementere:
em>"We also want it to be better. We're looking at all avenues. We understand the limitations of the current tech that's in the Deck, in terms of the screen. The screen's at the core of the device. Everything is anchored to it. Basically everything is architected around everything when you're talking about a device that small. I think it would be a bigger amount of work than people are assuming it would be. [...] I don't think we're discounting anything. But the idea that you could just swap in a new screen and be done—it would need more than that to be doable."</em>
Det vides endnu ikke om vi får små opgraderinger til Steam Deck løbende, eller om vi skal vente til en direkte efterfølger.
