During the past month I have been in discussions with a number of people at about.com.
I have been provided with the opportunity of writing articles on the linux.about.com subsite and I am in full control of all the content that will appear on that site.
It is early days and there is some old content on the site which is a bit out of date but I plan to make linux.about.com a great resource for everyone.
XBMC, which renamed itself to Kodi, is out with a new alpha release for the Kodi 14 media center software. While XBMC 13 introduced a lot of new features, Kodi 14 is going to be mostly about minor refinements.
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.
The official announcement of the Redux versions did note the Linux builds would come at a later date, but it may not be too far.
