Apparently director George Lucas has already confirmed that the film will be released before the end of the year and a new DVD box set of the entire Star Wars saga may also be in the works, possibly with "a new bonus disc containing deleted scenes from the original trilogy films."
Rebel Scum have posted a new flyer advertising the Burger King "Destiny Watches" promotion which kicks off on November 7th. Quoted on the flyer:
"To celebrate the complete Star Wars saga with the DVD release of Star Wars: Episode III - Revenge of the Sith."
Speculation may in fact point towards a DVD release of November 8th. Nonetheless, look for the release of Star Wars: Episode III - Revenge of the Sith before the end of the year.
