For every massive hype game, leak is bound to happen. Anyway it's still a relief to see the support of original games for our local scene.
The order for 360/PS3 GTA IV is actually more than Halo 3, according to Gamers Hideout.

Just few more days, and Rockstar is slamming down any GTA IV leaked media they can find. So...not to worry too much, just wait till the official release date and enjoy the game together.
