With Valve On Linux, Has LGP Lost All Relevance?
Aside from how Valve can better embrace Linux and open-source, another thing to ponder with Valve officially writing about Steam/Source on Linux, is the future of Linux Game Publishing.
Linux Game Publishing got a new CEO in January and aside from a brief company update in February, nothing new has come out since. The company hasn't released any new Linux game ports in years, their blog has been silent, and there hasn't been any rumblings of new projects to be announced soon.
Their most recent work was bringing Shadowgrounds and Shadowgrounds: Survivor to Linux, but that was back in 2009.
