Activision's departure from this year's E3 may have rocked the boat, but the convention is still on! Over 35 exhibitors have already confirmed their attendance, with more on the way.

Michael Gallagher, CEO of the ESA whose term has come under fire under the pressure of Activision's departure, has this to say about the event:

Clearly companies and attendees value what the E3 Summit offers that nobody else can—a professional and efficient experience conducive to getting the business of the video game industry done.

This continued support validates the Summit and is a testament to both the high level of interest and the important role it plays in our industry.
