Blu-ray.com, Amazon, Barnes & Noble, and several other retailers are listing new Blu-ray releases of all existing Star Wars movies (packaged individually, and not in 4K) for September 22, with a list price of $34.99 each. The runtime on the listing for ANH suggests that it’s the SE, but I suppose a GOUT bonus disc situation is possible. With a list price that high, I can’t imagine these are just repackaged 2011 discs without any additional content, but with the saga set all but confirmed for next year, I don’t know what else this could be.
EDIT: Actually, looking at the individual listings, I’m thinking these are probably just the 2011 discs with digital copies included, and probably new matching packaging. I’d love to be wrong though.
