these 40gb patches happen because they had to put assets in multiple times in such a way as to cause less seeking time on the internal hard drive. They're too slow this gen to be able to do this all without problems. So games would put various re-used assets in multiple places in the game's file bundles so that when you're in section A of the game it can access that file with all the other files of section A. And likewise it puts a duplicate in section B so that when you're in section B it doesn't have to seek to section A's files to find it, which would be slower. It sucks and caused some bloat in current gen games due to the duplication. Hopefully with these fast next gen SSDs that disappears.
