1up.com has a news post throwing together information from various sources, and revealing some release details about the Xbox 360. Scans of marketing flyers finally make clear the differences in the two skus. From the article: "There's ... a handy chart comparing the Core system to the standard system. The accessories are perhaps the most interesting, with specs and suggested retail prices listed. The wired controller is compatible with Windows XP, and the hard drive comes with some pre-loaded data, including an HD puzzle game. Of course, everything in the brochure is subject to change without notice, so check back for more confirmation as we get closer to the launch date."
