Gabe Newell has suggested that Valve won't support PS3 any time soon, despite Chet Faliszek's hopeful sentiments shared earlier this year.
"Platform investments, like the Mac, are difficult because you have to be aware of what direction that platform is moving,” said Newell.
"We need to target platforms that do a better job of looking like where we want to be in a few years."
"We would love to see the PS3 be more open like a Mac than more closed like a GameCube," he added. "It makes it easier to justify those investments if that were the case."
Valve recently released Steam for Mac and the Steam Play initiative to encourage crossover. Steam Play-enabled games can be bought once and played freely on both PC and Mac. Valve is now busily porting over the extensive, existing Steam catalogue.
Valve's Orange Box was produced for PS3 by EA in 2007.
