Well, Sony will still make a lot of money selling movies like Titanic, Superman, Aliens, and so forth, it doesn't really have to matter if these are sony productions or not. But all else equal for an average movie with X amount of sales and an average Sony movie wtih X amount of Sales, sony will want to put the Sony choice in because it will have a greater margin. It would be stupid not to take advantage of the places where you do have an advantage, read some Sun Tzu my friend.
So, if it isn't a sony movie then it's probably a more recent movie or a big one. Similar concept with music.
