With GTA IV being delayed (duh!) there are some possibilities that we might see a new trailer on the horizon and the reason why I became suspicious lately is because its been 3 months from the last trailer and if u do some math u will notice that the date of the first trailer was in march the second was in June and the third could be in....................September !! Yes that's right I said it !! And I add on that to make it the end of September !! Now sure all this calculation could be wrong but you never know, it could happen.
