[quote name='JolietJake']So what time does the E3 coverage start today? What sites are carrying the coverage?[/QUOTE]
Kotaku and 1up.com, and probably all the usuals have live coverage.
Microsoft kicks off at 10:25PM PST, 5 minutes earlier than scheduled, because they have a "last minute" announcement therefore bumping their start time up.
Supposedly it's "musically related."
