Just a suggestion 
If this game is set in 2007, then shouldn't they make it take place all over USA? Maybe we'll see if the Fort Staunton construction project was completed in Liberty. Who could be the head of the Leone organization, Joey or Toni? Who the leader of the Yakuza? Is Vercetti's organization still in control of Vice City. Is CJ still a gangbanger? Is Claude still residing in Liberty City?
