Is there a transformers war for cybertron demo for the ps3?

If there isn't one out right now than do you know if there is gonna be one later.Is there a transformers war for cybertron demo for the ps3?I don't think the game is far enough along for a demo yet, we havn't really seen to much even gameplay vids from it. Im sure there will be one eventually, with how poorly the franchise has done recently they would almost have to put one out to show its actually a good transformers game.
