i heard a rumour that the PC version has leaked, so i checked it, and some sites indeed confirmed that rumour

Grand Theft Auto: San Andreas PC Leaked

The PC version of GTA: San Andreas joins the list of games leaked before their release dates today - a good friend of mine pointed me towards a post on his blog which states that the game has been leaked on the Internet. According to the post, this seems to be a case of revenge:

Some Rockstar dudes got totally fired and stuff and were very pissed and all... so they decided to do this totally cool thing! They took whatever source they had as developers and posted it all over P2P and warez forums!

On closer inspection, I found out that the game was indeed released on many Warez forums and P2P networks, including Kazaa and eDonkey, among others. Apparently, the release is not one of the completed game, many players who have downloaded the leaked copy claims they have found many bugs in the game, including the (in)famous "Driver 3 flying car" bug.
it is said that they managed to recall the data, before many people could get it
i don't know if it's true ..but i certainly hope so (i'm already checking torrent sites )
