A new spring update for the Xbox 360 should be just around the corner, and if a list of alleged features leaked to Kotaku is to be believed, some kind of “motion sensor device” for the 360 could be on its way. The feature list gives no indication as to when the update is planned for, though if Microsoft follows the same schedule it did last year we can expect the update to launch early June.

Other interesting additions in the update include Windows Live Mail and Live Messenger video chat support, as well as the ability to store installation data on disk for faster loading and the addition of a media section for audio delivered through feeds. The full list contains about 80 new feature additions, tweaks and changes but was purported to be incomplete and subject to change. In any case, this is probably best left as a rumor for now, especially given that Microsoft has already labeled it as such.
