It seems like everything today is all about Linux. The latest is that a native Steam client was seen running at the Valve HQ, sans Wine. Previously, if you wanted to run Steam when you're running Linux, you'd have to go through a emulator (basically) called Wine. This is often troublesome and time consuming, and also decreases performance. A native client would be as simple as installing a program, and it looks like Valve plans on porting over its titles to run natively on Linux, like they did for OS X.
For a while now there have been rumors floating around about this, but none were confirmed until now. Thanks to Michael Larabel, the founder of a Linux-centered tech website who was recently invited to the Valve HQ to see the native Steam Linux client running, we know this is true. A rather big surprise is that Gabe Newell, co-founder of and managing director at Valve, is personally working on this project. Apparently he isn't so hot on Windows 8.
There's no release date set, since this is Valve we're talking about, and it's looking like Left 4 Dead 2 might be the only title available at launch. It's expected that there will be a beta released before the official launch, so hopefully we'll all be able to try this out soon.
