I imagine for the PS4 at least these will end up online at some point given piracy is possible on the PS4, meaning people will share / preserve content. Even if you did have a PS4 you'd have to update it to download the content, which patches any current exploits you could use to explore the hard drive.
Although it is possible to explore the Xbox CDN servers with some open source tools, I never had much luck with that.
So consoles have potential, however content sharing is not that easy for current gen PlayStation's and Xbox's yet.
