Not really. Years ago people mentioned they found extra code for what looked like a linux version somewhere in some steam package or development kit or whatever it was. This was years and years ago. Valve downplayed it. Of course now it's obvious they've been planning and experimenting with linux this whole time. They've gotten higher frame rates in Left 4 Dead 2 on Linux than on Windows on the same hardware so, they have quiet a vested interest in this thing. I think they're in this for the long run. The biggest threat to consoles is Steam and consoles after all, are just crippled PCs.
