This is a pretty big deal, it seems, as it is (to my knowledge) the first time HBO content of any kind has been available (free or otherwise) without a cable subscription while it is still "in season" (prior to its DVD release).

Perhaps indicative of looser restrictions on HBO going forward, or a partnership between HBO and Xbox Live that allows Xbox Live Gold to be treated as a "cable subscription"?

Time will tell, but at the very least this is an exciting way for people without HBO subscriptions to keep current on one of televisions best current shows.
