Well now this is quite interesting, a friendly tip came in today that there is now a Linux SDK for CryEngine.
Today Linux has been added into the list of operating systems that it supports (taken from SteamDB
So, could it be that CryEngine is actually about to announce Linux support? Seems not so far fetched now with this new information.
This would also be good news for the Kickstarters that came in recently using CryEngine that have planned Linux support (maybe they even knew this already, but couldn't share it).
Of course a SteamDB entry is not confirmation, but it does go some ways and it does usually turn out true. Interesting that this lands on Steam's one year anniversary.
This is what happens when such a big company pushes Linux so hard, people jump on board.
