We're not sure how, but it appears that some body's managed to grab a copy of Grand Theft Auto 4 (Xbox 360, PS3) before its scheduled launch for this month.

This much we know, based on a gameplay video we picked up on the net for the game's PS3 port. The clip doesn't show any of the combat sequences unfortunately, though it does give us a first look at the GTA4's opening cinematic.

The video also gives us a glimpse of how the game's graphics which, we have to admit, look beautiful despite the rather low quality of the video stream. We remind the readers that GTA4 is currently expected to launch this April 29 - that's just six more days of waiting.

Until then, feel free to watch its gameplay footage, available for viewing below. Enjoy!
