Joining Vivendi, Activision, and LucasArts in their departures from the Entertainment Software Association is DOOM and Quake developer id Software. The popular PC game developer confirmed their departure with GamePolitics earlier today. Though still unconfirmed, it's very likely that id's departure will result in their absence at this year's E3 Media & Business Summit.

This latest exit poses a serious question -- with four key members departing within weeks of one another and more exits possible, can the ESA still survive?
