Xbox 360 spring update coming May 19?

If you've run out of beef jerky and had your free Hulu Plus trial go bust, you're certainly not alone. Don't get bored: more bits of new hotness are coming to your console, and they're coming soon. An internal document leaked to our good friends over at Joystiq looks to confirm that the big Xbox 360 spring update will hit on May 19th. However, it'll come in six "separate groups" to "ensure a high quality deployment," so you might not get it until the end of the month, and everyone will have to wait until May 27th to get Avatar Kinect. What else is new? Well, there'll be the slightly larger disc format and support for PayPal, opening the door to a bold new world of personal finance information able to be hacked from your console.
