Rockstar themselves usually doesn't release information directly to the public. Information is given by Rockstar to a news source who provides it to the public. For about another month we'll be seeing magazine previews only. Once we get into the summer, you'll be seeing new previews every week. In 2004 GameSpot had San Andreas Saturday where every Saturday they would have a new preview up based specifically on one aspect of the game. Perhaps we'll see the same with GTA IV. There's just so much more to know.
