Unfortunately that refers to the CMS installation files for Linux, not a Linux player.
All I can say at the moment is that creating a player is complex, particularly for Linux, so we need to make sure we get it right. This is the 4th rewrite in total for Linux
We will make an announcement on the post linked above when there is a progress update. Meanwhile you could apply to join the beta testers group, who will receive early access to the player once available.
