Ars Technica reports on Sony's plans for their online service. As previously discussed, they'll be offering online play for free. They hope to make money via an e-distribution system. From the article: "Yet it is unclear what Sony intends to sell. While the 60GB hard drive in the premium console is spacious, it would not be large enough to hold a collection of HD video, although the company could sell storage add-ons in the future. We believe that Sony will initially sell other content, including music and standard definition video, as well as gaming content such as that available today in the Xbox Live Marketplace."
