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.
The only reason I want the Deck 2 to release is to get a cheap Deck 1. I don’t really need one, so I’m not paying the price they’re asking for it. If 2 comes out and there are some cheap 1s people are getting rid of, I’ll probably snatch one up. Other than that, I think it plays about any game I’d want to play on it.
