It's springtime again, which can mean only one thing. No, not the impending arrival of young couples making out behind the bushes at the park, it's time for Xbox 360 Spring update rumors. Clan support has been a rumored addition for a while now, and there are even some alleged pictures of it in action (see above). Before we define this a little further, let's just get this out of the way: clan support is not part of the upcoming spring update. This was confirmed by Major Nelson himself during our latest Xbox 360 Fancast.
Now for clarification's sake, it's perfectly possible for any given game to have clan support. As such, screens like the one above may be legitimate. However, Major Nelson informed us that Microsoft has no plans to integrate clan support into the 360 itself. In other words, there are no plans to add universal clan support that spans multiple games. Clan support is offered by Microsoft, but it is up to developers to implement it into individual titles.
So, there you go, no clan support in the spring update. Of course, that doesn't stop us from speculating about other features.
