PlayStation 3 is now officially 599 US dollars--and only 599 US dollars. In a move that surprises absolutely no one, Sony has officially discontinued the cheaper SKU. Dave Karraker told GameDaily BIZ: "Due to the overwhelming demand for the 60GB model from both retailers and consumers, we have ceased offering the 20GB model here in North America. In addition to the larger internal hard drive, the 60GB PlayStation 3 features added storage media slots and built-in Wi-Fi not found in the 20GB system. Based on retailer and consumer feedback, we have decided to focus our current efforts on the more popular 60GB model."
