The problem is "Linux" has only been mentioned once that we can see, and that's on their Steam coming soon button. It's not mentioned in any other announcement or their FAQ, but this is still on their official site.
Metro 2033 Redux is confirmed for Linux, but the actual release date isn't certain yet. Luckily thanks as usual to the excellent SteamDB it looks like it's coming sooner rather than later.

Mozilla Firefox 32 Officially Released
It's been a little over a month since the previous Firefox stable release and the developers have now pushed a new major update to users. This latest iteration of Firefox brings just a few major features for regular users, but it excels in other areas like better HTML 5 support.
The official announcement for Mozilla Firefox 32 hasn't been made public just yet, but the mirrors now host the latest stable versions.

M[icrosoft] has deliberately violated the laws of competition in USA and elsewhere repeatedly, systematically and with malice. They are out to get us. At first they got an exclusive deal with IBM to get their foot in the door, piggybacking on IBM’s branding with business, then they demanded exclusive deals with ISVs and manufacturers, then they punished any manufacturer who stepped out of line and installed competing products, then they created an endless chain of incompatible file-format changes and created whole industries based on the existence of overly complex secret protocols and finally forced the world to accept a closed standard as an open standard… That whole burden has served to render IT more expensive to own and to operate and much more fragile than it should be just on technical merits.

Regardless of what Free Open Source Software (FOSS) you need to use, you might not always find it the most natural evolution -- especially when you've spent the whole of your career using proprietary software.
