The xbox 360 has been hacked within 48 hours.

For the first J-Tag or whatever they are going to call it to be released is going to take longer; because once they have the base of the hacked firmware they aren't starting from scratch creating it over and over. It's like how jailbreaks work, it took a month for the first one for the iPhone 5 to come out; now they're out a day or 2 after the new firmware is released.
