It's expected that the recently revealed demo of the Xbox 360 version of RTS Command & Conquer 3: Tiberium Wars will be released on Xbox Live today.
An admin on the official C&C forums gave the date for the demo in a thread about a new Tiberium Wars game trailer and further downloads hitting Live yesterday.
As yet we've heard nothing from EA on what the demo will contain, but it may end up being the same as the PC demo which featured one tutorial mission, two single-player missions (which included some of the game's live action video sequences), a skirmish map and a live action trailer montage featuring various famous actors who signed up to star in the sequel.
