Blurays are always 1080p because if they arent they dont fit in th Bluray standard and the nname Bluray cant be used anymore. I never saw a Bluray without 1080p.
Bluray has to be 1080p if not then there would be atleast 1000 people i n the USA try to earn some money and sue Sony and all the other Bluray Companys because they were betrayed. bluray is always 1080p if not its not an original bluray.
