Think Rockstar Games has a lot riding on the upcoming release of Grand Theft Auto IV? You would be correct. According to Variety, is looks like the Take-Two, Rockstar’s parent company, is expecting to rake in over $400 million during the first week of sales. Whoa! That would equate to roughly 6 million units sold over 7 days, which is a pretty insane number, especially given the state of the economy, but if anyone can pull this off it’s the Grand Theft Auto franchise. Given the new dual-platform release approach, coupled with the incredible hype surrounding the impending April 29th drop, epic sales are no brainer, but $400 million? We’ll just have to wait and see.
