How does the PS3 remain as the only unhacked system? And for how long?

[KZ2]

The cost of BD Burners are expensive and the cost of Blank BD are expensive that deters people from hacking the PS3. A tool to open up the PS3 costs about the same price as the PS3 console itself also another deterrent to hackers. Opening PS3 automatically voids the warranty. Hacking the Wii, X360, older consoles and the portables is really cheap.
