It's a week and change before E3 and rumors are already flying. The scheduled outage of Xbox Live on Tuesday is leading some people to guess that Microsoft is finally releasing the update that allows people to download marketplace content in the background. This makes sense, seeing as MS providing loads of E3-related content on Xbox Live during the event.
Along with the improved downloading, another rumored feature is the ability to send voice and text messages to people during games. Isn't this already there on dashboard?
