Although they're all planned to arrive in the autumn, Microsoft won't be launching Facebook, Twitter and Last.FM channels on Xbox Live at the same time, it says.
Speaking to CVG at a London event this afternoon, an Xbox spokesperson said: "We'll spread them out to a degree, although obviously they're all launching in the autumn.
"We want to try and not put them on top of each other, so each can have its own breathing space."
When they eventually do launch, the new channels will allow 360 owners to post "tweets" on their sofa via Twitter, and upload game screenshots to show friends on Facebook. See them both in action below.
