I dont know how they will or if they can stop the illegitimate people at this stage in the game.
Without a CD key or some form of authentication, im not sure how they can stop people. Requiring the CD is easily bypassed. Unless there is an included 'file' of some sort on every CD that is unique. But that is easily bypassed as well.
I think they should do whatever they can though. If you warez a game, play it, like it, and dont buy it. Then youre scum and should be drug into the street and stoned to death.
