GTA IV trailer this month

Rockstar has revealed we'll get our first look at its next-gen gangland adventure on 29th March, when a trailer for Grand Theft Auto IV will be shown across the Internet horizon.

Rockstar was unable to comment on what exactly we could see in the trailer, though we're sure it will be enough to ruffle Jack Thompson's feathers and make us dribble a little excitement in our news-pants.

Hopefully it will also mark the start of a real campaign for the game kept so rigorously under lock and key. All we know so far is that it will be launched simultaneously on Xbox 360 and PS3 in October, and that exclusive downloadable content will be made available for both systems.

However, it's likely that the game will be built on the same RAGE engine that powered Rockstar's excellent Table Tennis foray last May.

We're also wistfully trying to believe rumours that the action will take place in London this time, marking the series' first 3D foray outside of America. We can but dream of a car-chase through Albert Square, or punching Martin Fowler in the chops outside the Queen Vic.

But other than that, you'll have to wait and see.
