Blizzard Entertainment’s parent company Vivendi Universal, who also recently acquired Activision, appear to have made a sweeping change in dropping the once popular E3 (Electronic Entertainment Expo) from their calenders permanently. Both Blizzard and Activision have stated that they plan not to attend the event this year, which must come as quite a blow to the ESA, the organisation that is behind E3. In recent years E3 has been trying to remodel themselves due to huge costs and swarming numbers of gamers previously swooping in on the glamour and glitz of a legendary highlight of the industry, and have moved to a more isolated invitational gathering of reporters, reviewers, and game studios.
It looks like in the future that Blizzard themselves are going to be holding the majority of their own functions and public events, so expect the BlizzCon tradition to continue for quite some years to come.
