Possibly, the ESA relied on it for revenue. Though PAX is run by a for profit event company, I think. PAX is better at managing a public event. E3 wasn't originally open to the public, and once they opened up it was never done very well. If publishers want to have that public convention thing, PAX is better. Letting the public in to E3 sort of ruined the industry insider aspect of the convention, all the meetings moved to hotel rooms so that people could hear each other.
