Unfortunately, a major caveat reveals that not everyone with an Xbox 360 and Gold membership will be able to enjoy the content. According to ESPN3.com and the press release announcing the partnership with Microsoft, only certain Xbox 360 owners with participating ISPs will be able to receive the streams.
Xbox Live Gold members who have high-speed Internet service from an affiliated service provider will enjoy more than 3,500 live sporting events from ESPN3.com--ESPN's 24-7 broadband sports network.
Among the people this affects are New York City area Time Warner Cable and Cablevision subscribers. For a complete list of participating ISPs to see whether you'll be left in the dark, check out ESPN's list here.
