Source is KeplerL2, who is generally considered a reliable source for insider hardware info, particularly on AMD GPU hardware and AMD SoC for consoles.
Previously I would have personally estimated Steam Deck 2 to release mid 2026-early 2027, but the recent info about an upcoming Steam Machine made me think that maybe I should push back that estimate.
Of course even if we assume this is reliable insider info, a lot can change in couple years, so things can definitely change.
I don’t want a new steam deck. I want a new steam controller and for valve to announce steam machines 2.0
Then we can finally watch windows die a (probably fairly slow, but steady) death.
New steam controller was leaked earlier this year, and leaks for the new steam machine came out a few days ago. So you’ll get your wish pretty soon probably.
