According to a Rockstar representative at the PlayStation Holiday Preview Event,
This news comes with many implications. For one, Rockstar mentions "at least 16," which means no less than 16 is aimed for, but there is also the potential for more. This information also confirms once more that deathmatch isn't the only option in multiplayer. Will we see racing? Capture the Flag? Or something even more intuitive? Only time will tell...
Set for 2008’s second quarter, GTA IV was also missing, but Rockstar’s man on the scene told GamingExcellence that they had begun testing the various plots and that the developers were considering the possibility of having an open world completely unlocked from the start of the game. We also understand that the game’s multiplayer mode, unseen in the GTA franchise since GTA2 in 1997, is aiming for at least 16 simultaneous players, with more than just the usual deathmatch mode.
