The following is schedule of events for Square Enix Presents E3 Livestream
As you can see they will be talking about their entire announced lineup, as well as continuing to work with Deep Silver in promoting their games (Square Enix & Deep Silver shared a booth at PAX East). Plus, as reported all over the internet they will be talking about the next generation of Final Fantasy on Tuesday morning as well. So plenty of interesting stuff from Square. I believe it will be livestreamed on their YouTube channel. I am personally excited to see the English build of Kingdom Hearts HD, Thief & hear more about Murdered: Soul Suspect. Source.
