Your still missing the point. Even if they are making more by cutting out the middle man they are still losing out in sheer numbers. Say you have a family of 4 and go to the movies. You are buying 4 tickets. If you are buying the same movie on VOD do you think the one time purchase is going to be anywhere close to what they would get from even getting half of the money from 4 individual tickets? Not even close. Even if it is just a couple going to the movies your still cutting that in half with VOD. That and the simple fact people at home are not going to pay huge amounts for new releases so the profits go down even more.
Yours totally wrong on thinking the studios don't need the theaters.
