@medamax It will not include WINE. It will not be in the official repositories, of course there is nothing preventing one from installing WINE on SteamOS...but it's kinda missing the point. Like every other linux distro, there will be third party repositories and most definitely one featuring an easy WINE install. There is good news though, OpenGL/OpenAL is as fully functional as DX and the advent of Mantle means many good things as well. So there is the possibility of games migrating away from DX if SteamOS and Mantle take off. Mantle seems like a good bet now given it's performance increases and the fact that the next gen consoles will need to take advantage of it for maximum performance. So there are two answers to your question: 1.) SteamOS will never support all the games currently in your steam library, nor will it support WINE integration 2.) You can install WINE if you choose but it will probably be a chore for average joe schmoe to figure out the dependencies, but like every linux community, a third party repository will quickly scoop this and do the work for you. So it's a NO from an out of the box perspective, but there is nothing preventing WINE integration and it will assuredly be packaged by someone.
