Well, there is some teasing along those lines there:
> Watch for announcements in the coming weeks about all the AAA titles coming natively to SteamOS in 2014.
But more importantly, control of Steam gives Valve a lot of leverage in this. It's easy to see the reasons for Linux support in indie games. But harder to see why mid-tier developers like Paradox or Eugen started to port their latest games to Linux. It's a good bet that some kind of a Steam-related carrot was involved there.
