Neither can I. We've seen screenshots, trailers, features and a lot of other stuff. But the most important thing is the game.
Quick summary:
GTA IV was supposed to be released on October 19th 2007 but was unfortunately delayed due to some difficulties, however R* could've added more new features, fixed any bugs etc. Over the months we've seen new trailers and screenshots and one day, R* announced the worldwide release date for R*'s most anticipated title ever, GTA IV. Tuesday 29th April 2008. A day that will go down in history for all to remember. People will be waiting in a long queue at their
local game shops to buy the game.
