A fan has made an interesting discovery; Steam has registered some Xbox subdomains.
These subdomains include the very clearly Xbox related xbox.steamgames.com and xbox.steampowered.com. Our source can only speculate on what these domains are for, if they are planned to be used at all.
Reddit is sharing their theories on what this could possibly mean. Yvese believes this will allow Xbox account owners to connect their accounts to Steam. This is the top comment on the thread, and for good reason. Valve made such arrangements with the release of Portal 2 in 2011 on Steam and PlayStation 3. Portal 2 remains the only Steam game connected to a console, offering features like cross-platform matchmaking, gameplay, friends, chat, Steam achievements, and even Steam Cloud save.
