Paul Thurrott, a known Microsoft fanboy, has released information he claims is accurate for the upcoming Xbox 720. Most will remember that Thurrott was the first to announce that Microsoft changed the launch date for the next Xbox from April 24 to May 21. Interestingly enough, Microsoft unveiled the May 21 event on April 24.
Thurrott expects (claims?) that the Xbox 720 will be released sometime in November with two pricing versions. For $499, you get the console flat-out. Or, you can buy the console for $299 with a $10/month two-year Xbox LIVE Gold contract. The $299 version ultimately ends up costing $539.
Thurrott also says that the May 21 event is just a teaser and that the full unveiling will occur at E3 in early June 2013. You can read all of his claims on the WindowsITPro site.
