All three movies from the TV Series "Stand Alone Complex" have recently gone up for Pre-order on Amazon America with an upcoming release date of 21st June 2011 and a price of $24.49 for each Blu-ray.
Previously the Ghost In The Shell: Stand Alone Complex movies were only available to buy from Japan in a large "S.A.C." Boxset, which featured all three films in 1080p High Definition with Japanese Soundtrack & English Subtitles (main movie(s) only) which resulted in a Japanese Retail price of around £150.
No information on region coding (as of yet) but if these films are being Distributed by Bandai Entertainment then they will most likely be region locked to USA (Region A) - however we will not know until after the films are released.
