Not sure what to make of this. Bullshit radar says "proof of nothing" because there's no reason for tech support to be looped in on a game in development. That said, two guys worked up an extremely patient, social engineering prank that had 2K Games support believing, or at least suspicious of the possibility of a hacked Grand Theft Auto IV demo on pirate sites. And in the back-and-forth, it turned up this reply from tech support:
"The PC version of GTA IV has not even been announced for release and is still in development so is not about to be released on a website."
