Dmac_91 has posted on our forums that CVG have some high quality screens up on their site. Unfortunately there aren't any new shots, and the screens all have huge watermarks over them. They've come from a disc that was handed out to the press in Rockstar's meeting rooms at the Leipzig Games Convention in Germany. This of course means that other press members will have the screens, so we'll add them to our gallery as soon as we get our hands on unwatermarked versions.

UPDATE: It seems the page and screenshots have been removed. We'll try and get the screens added to our gallery as soon as we can.
Here's the link to the topic if you want to see the pics, Jace
