When the first GTA came out nobody outside of gaming geek circles really cared. The first two were pretty well selling games, but nothing spectacular. With number three they finally reached the market of "people who don't like games, but enjoy the idea of shooting people" and sold octopule digits. =P
But yeah, GTA4 is bound to attract the same huge crowd that loved the last three parts, although sales will probably be lower due to the HD consoles still being out of the casual gamer's price range. And make no mistake, the huge sales of the GTA franchise came mostly from people who don't play other games much, in other words casuals.
Here I go, blabbering completely off-topic again. ;__;
