I read that pre-sales and initial shipments totaled 5 million copies, 4.5 million of which were sold on the first day. At $60 a pop (more for the deluxe edition) thats almost $300 million for the opening day. If the game makes it to 8 million copies throughout its duration, which is very well could end up at, then it will gross over $500 million, which is only bested by Titanic and Star Wars for total takes for a movie. The video game industry is really taking off, and will overtake the movie industry in a few years. As time goes on, we are going to see more and more money put into game development, which means we will see alot of really nice games in the future.
