Nope not too sure. In my opinion, yes they will work. But not once they are released. It will just take time to hack the firmware, and then once it has happened, it will be released to the public. Either way, it will be hacked somehow. Hackers will learn, and they will hack it. Then the company will learn, and will counter it. It will just keep on going until in the end, one of them gives up.
Usually, when the hacker gives up, another new hacker team comes and hacks it up. Or sometimes, there will be too many hackers to handle, and the company will simple give up xD
