Major Nelson announced on his blog that Microsoft’s E3 press briefing, titled Xbox: Entertainment Evolved, can be seen live on Xbox Live for the first time ever. It will air Monday, June 4 at 12:30p ET/9:30a PT, both on Xbox Live and Spike TV. We don’t know what to expect this year, besides a new music service and the lack of a new console, but Microsoft will likely cram a lot into their 90-minute slot. Our hopes our high that this year’s conference gives some attention to XBLA, which was sadly missing from last year’s showing. Be sure to catch the conference live, and check back here during E3 for all the breaking XBLA news straight from the show floor.
