Following reports last week that the second disc of the PC version of Modern Warfare 3 had been leaked (a leak incidentally that no one could find), we can now report that the first playable version of the game really is available online.
The Xbox 360 version (which appears to have been made available just a matter of minutes ago) comes from a non-scene P2P release group and weighs in at just over 8Gb, region free, stealth patched and ready to go.
Guess it was going to happen.
