We're liveblogging Microsoft's E3 2012 keynote at 12:30PM ET!

E3's about to get real, y'all. Microsoft's getting this party started with today's Media Briefing at 12:30PM ET. Will we be on hand? You can bet your Smart Glass we will be. Our crew is going to be liveblogging the whole thing, and you can follow along right here. What can we expect from this year's event? Most likely we won't be seeing a successor to the Xbox 360 just yet, but we're sure that Microsoft's got plenty up its sleeve this time out. Stay tuned!
