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.
When I first got the steam deck, I thought it was so great and used it all the time; I still do.
I told my wife that I liked it so much that I would buy the next one as soon as it released.
After having it for some time, I realized that all the games I play run on it easily and there is no real need to upgrade.
So, I plan to use this steamdeck until it it stops working. I imagine that will be a while as I’m going to repair it when/if something breaks.
