Valve's stance on developing for PlayStation 3 may have softened, judging by comments from Left 4 Dead 2 developer Chet Faliszek last week.
"Before we do anything on the PS3 we need to be able to support it in the right way," he told Edge.
"But we'll look at it, and I'm sure down the road we'll do it."
Although The Orange Box was released for PS3 soon after PC and Xbox 360 versions, the conversion was undertaken by an EA team rather than Valve, and the results were mixed to say the least.
Valve has been very down on the PS3 in public, with boss Gabe Newell having labelled the system "a horrible disaster" prior to the release of Orange Box.
Later in 2007 Newell described the system as "a waste of everybody's time", apparently because figuring out the console's systems wouldn't reap any long-term benefits beyond the borders of PS3 development.
