Warner Bros. has announced the The Big Bang Theory: Season 3 DVD and Blu-ray will be released in the U.S. on September 14th, according to TVShowsOnDVD.com.

The DVD will contain 3 discs and the Blu-ray will hold 2. The episodes will be presented in widescreen on both, with high definition quality on the Blu-ray. Audio is reportedly English Dolby Surround 5.1 for both, which would be an improvement for the DVDs as they previously enjoyed only stereo audio. A Portuguese stereo audio track will also be included.

Extras are a Gag Reel, a tour of the set with Simon Helberg and Kunal Nayyar, and a "Take-Out with the Cast of The Big Bang Theory" featurette including interviews with the cast and crew. The cover art work isn't yet available.
