Zařízení Steam Deck OLED bylo znovu naskladněno, ale vlivem rostoucích cen pamětí a úložišť má novou, vyšší cenovku. Steam Deck OLED 512 GB stojí nově 779 EUR (stál 569 EUR) a Steam Deck OLED 1 TB stojí 919 EUR (stál 679 EUR). Samotné zařízení se nijak nezměnilo a nové ceny tedy pouze odráží aktuální náklady na komponenty a další globální logistické výzvy, se kterými se potýká celá branže.
