Sure, I haven't taken Business Mangagement class, but I think PD isn't really playing around and wasting money. I mean, if they did, GT4 would be released in Christmas 2005. I think PD wants to market GT4 in several ways. I don't think Polyphony D. isn't trying to spend more time on marketing than making a world-class video game. Who knows? Next thing you might see is commericals about a game still in production. Do you remember the GT3 commercials? Same might happen for GT4. I'll be watching WWE Wrestling, then their HORRIBLY REPETITIVE COMMERCIALS will be on, and I'll probably see the same damn commerical... 4, 5 times.
Either you think it's marketing strategies or just goofing off, I think GT4 will be in stores within the next few months. I know I heard "Fall 2004," but I think it may not mean "Christmas '04."
