Even before that new app smell has worn off from Hulu Plus, Microsoft will launch its annual spring update for the Xbox 360 Dashboard. Images sent to Joystiq by a Microsoft tech support employee reveal that the next Dashboard update will begin rolling out on May 19.

According to the documents, the update will be distributed in six separate waves between May 19 and May 30 "to ensure a high quality deployment." Additionally, while not technically part of the automatic update, Avatar Kinect is listed for a May 27 arrival as a separate download.

Aside from offering support for the new Microsoft disc format -- which will "be used in future game titles releasing later in 2011" -- the spring system update will enable PayPal support on the console, extending the payment option "to new international markets." PayPal will be "the only user facing feature" of the update.
