According to Amazon, both the DVD and Blu-ray versions will be available on September 4th, 2012, which is 17 days before the Season 5 premiere date.
But tread cautiously, as last year fans were promised an earlier release like this only to have it show up just days before Season 4 began. Regardless, it's good news, and there's no time like the present to get ordered-up. The DVD set is priced at $41.99 and the Blu-Ray set at $48.99.
