fragMasterFlash writes: Valve head—and one-time Microsoft employee—Gabe Newell has branded Windows 8 "a catastrophe for everyone in the PC space" at videogame conference Casual Connect in Seattle. The Valve boss continued, saying that in the fallout from Windows 8, "we'll lose some of the top-tier PC/OEMs, who will exit the market. I think margins will be destroyed for a bunch of people." He argued that one of the last remaining things keeping people away from Linux was the lack of games. Valve is working to bring Left 4 Dead 2 and other Steam titles to Linux in a move that Newell describes as "a hedging strategy." If his predictions about Windows 8 come true, he says "it will be good to have alternatives to hedge against that eventuality."
