What a coincidence! From DVDFile:
February 11
Street date alert - 2:36pm
[snip] On 3/19, Buena Vista will release the director's cut of Stone's acclaimed biopic, with the same transfer and features as the edition previously available only in the box set. (The movie only edition of Nixon will remain on the market as well.) Retail is $29.95.
Thank you, Buena Vista!
