It could be like the Dragon Age 2 thing.
There is a version of SecuROM that just checks release date type stuff - it prevents you from playing the game early. After that it goes away and doesnt do anything. It is NOT the root kit version of SecuROM, its a completely different program made by the same company that unfortunately has the same name.
Thats speculation on my part, but given the "no DRM" statements being made by everybody, its a good bet I think.
