So far we have the following confirmed conferences for next month.
- Microsoft - June 9 at 9:30AM (PT)
- EA - June 9 at Noon (PT)
- Sony - June 9 at 6:00PM (PT)
- Nintendo (Not a live conference, online streams only of E3 content) - Starts June 10 at 9:00AM (PT)
As of right now, Ubisoft does not yet have a time or date announced for their conference. There is no word on whether or not Konami will be holding a live conference. Last year, their main conference was held days ahead of E3.
I can only hope that Ubisoft and Konami both hold their events on June 9 and just completely tie up my entire day.
