There's no evidence to prove that they're working on their own Linux powered gaming console and even if they were, it's still a Linux powered console at the end of the day and people will find a way to reverse engineer anything Linux based that Valve put out. So I would argue regardless of whether or not they develop a Linux console, that would still be a massive benefit to the Linux community. If Valve a company that EA tried acquiring at a valuation of something in the vicinity of one billion dollars sometime ago isn't a major player, then you must have very high standards. Valve have produced so many cult classics and well-known titles that even years after being created are still played, modded and purchased — Counter Strike and Half Life anyone?
