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.

By definition it cannot exist. You can have a powerhouse or portable. The fact that they made the deck as powerful as they did is frankly amazing.
The ROG Xbox Ally X is rumored to target 1080p at $899.99, ONEXPLAYER has models using the latest and greatest AMD AI 9 HX and 144hz at $900~$1K-ish, Aya Neo and GPD Win have some too.
There’s plenty options for “Powerhouse portables”, you just gotta be willing to pay for 'em.
