I am not a very knowledgeable person about hacking or encryption. But as far as i understand, taking a large encryption head on is useless. Instead of breaking some big encryption, a better approach is to find vulnerability/loop holes/flaws/back doors in a system. That's how PS3 was jailbroken in first place due to unique flaw in firmware 3.55. Similarly, XBox 360s had a vulnerability of their DVD drives. Companies have gotten smarter and making their system very close gated. Its very hard to find loopholes and flaws (unless they make some dumb mistake). Also encryption will only get stronger with time goes on. At some point it will be pointless to take encryption head on. But i don't know how hacker community thinks and operate. Maybe someone who is actually a part of this can give you a better idea.
