The Xbox 360 update for Spring 07 is almost here and several new tweaks and features for the 360 will be introduced.  Microsoft will be introducing tweaks to the messaging abilities of the 360 and even releasing a new thumb keyboard for messaging.  Should help make the "Live Anywhere" service that much better.  More improvements on background downloading, and even more support for h.264 and MPEG-4 video formats are among some of the other improvements.  For a full list of improvements just follow this link.
