Major Nelson tweet reporting for duty, sir. Latest tweet intelligence reveals that the Xbox 360 addition of Facebook, Twitter, and Last.fm (due to be available tomorrow) will not require an update. The new features will instead be magically inserted into your console via tiny underpaid mice while you sleep. The Major’s exact words below.

“When we turn on the new features tomorrow they’ll just appear! No need for a system update.”

There you have it. So, whatever you do, don’t kill any rodents tonight.
