Valve has reconfirmed that the Steam Deck UI is set to replace Big Picture mode on the desktop client, and it now says this update is coming "soon".
"The work that has gone into Steam Deck’s user interface will soon be available through the desktop client, as a new version of 'Big Picture', the version of Steam that’s meant to be used with a game controller and on a television screen," Valve says in a newly-published booklet for its portable console.
The exciting bit here is that Valve now says this update is coming "soon." (Though you may need to multiply by Valve time.)
Steam's current Big Picture mode basically gives you a console-style interface to use when your PC's connected to a TV. The basic design of the UI has remained the same for years, even as the main desktop Steam interface has continued to evolve, and the Steam Deck UI presents a much more modern version of that concept.
Valve has also recently noted that it's working on "improving the docked experience for Steam Deck with all USB-C hubs and external displays," even as the official dock has been delayed. Those sorts of improvements could tie neatly into a broader update to Big Picture mode.
If you're still waiting for your portable, there's good news. Valve is continuing to accelerate Steam Deck shipments.
