Source Engine on Linux - the likely future

The site hl-inside .ru conveys that Valve is going to port the Source engine to Linux. The information is based on the approval of the leading site Phoronix , specializing since 2004 on everything related to this platform.
Last year, rumors were already circulating that Valve might be engaged in porting Source of games, after they started looking for a programmer, one of whose duties should be “porting Windows games to the Linux platform”. However, since then, developers have not announced the release of the Linux-client of any of its product. And nevertheless, Phoronix say that they received insider information that Valve is now engaged in exactly this process. The Source engine was originally designed as flexible and scalable, which should make it very easy to add support for OpenGL, which is used on both Linux and Mac OS X.
In support of his words, Phoronix cites the fact that Postal III, developed by Running With Scissors on the Source engine, will also be released for the Linux platform (as well as for the Xbox 360, PlayStation 3, PC and Mac). Phoronix has no other facts to assert, except perhaps for its untainted reputation. The only other thing they mention as a confirming moment is in the blog of one programmer, Ryan Gordon, who is engaged in porting numerous games to Linux (Unreal Tournament 3, Duke Nukem 3D, Shadow Warrior, Quake III Arena, Unreal 200x, Call of Duty, Medal of Honor , America's Army, Postal ½, Battlefield 1942, Serious Sam, and others) The Weighted Cube pal from Portal was seen twice.
