IGN's main feature today for day 2 is the rare interview with Leslie Benzies.
It's pretty informative in that it seals a lot of the wants and desires and hopes Rockstar has for this new entry, the biggest revelation of which being tied to multiplayer.
A choice quote:
“GTA III was a technical revolution when new technology allowed us to break away from the norm and create something special. We consider subsequent refinements of the series to be revolutionary in their own way, in terms of playability, scale and narrative. For GTA V we want to push all of these to a new level while incorporating new gameplay elements that would not have been possible before. The ability to switch between different characters allows the player to do things that wouldn't have been possible in any other GTA game, and on the multiplayer side we hope that GTA V will do for multiplayer open world games what GTA 3 did for open world single-player games.”
