Some are surmising that SteamOS will be 12.04 (Precise) since the public Steam-Client for Linux is only distributed for that version. This doesn't mean they wont build for 13.10 then release that for public access.

It would be bad advice for any Linux coders in Valve to suggest sticking to an old version of Ubuntu as that would bring about turmoil involved in a transition from XOrg to Mir.
