According to Michael Larabel of Phoronix, Valve is developing a Steam client for the Linux operating system. The story began to take shape last month when Larabel tweeted that Valve's Gabe Newell had reached out to him about a Linux build of the client software. Today Larabel tweeted that he flew to Valve headquarters in Bellevue, Washington for a personal meeting.
"Steam is coming to Linux," he replied in response to a question on Twitter following that announcement.
Another tweet revealed that Valve has a whole bunch of plans related to Linux:
"#valve does have Linux games coming plus other very positive Linux plans... I'll briefly post some screenshots and such tonight."
Those screenshots have yet to be posted. On top of all that, a post in NeoGAF forums details Larabel on Phoronix IRC talking about his tour of Valve HQ and that he ran Linux binaries of the Steam client himself while there.
Hopefully Larabel will release those images at some point soon to further confirm his public statements on the matter...
