Blizzard’s annual convention BlizzCon looks set to return this year as IncGamers has been tipped-off that the event has a tentative date and location set for later this year.Earlier this year there was speculation that the event would move to Las Vegas but these rumours were squashed pretty quickly by Blizzard. Today the Anaheim Convention Center has listed this year’s BlizzCon as taking place 22-23 October after the date suddenly appeared on the Anaheim Convention Center website earlier this evening.Spotting the error, the Convention Center immediately pulled the dates from their website. IncGamers contacted Blizzard who were quick to dismiss the booking listing as you’d expect.Blizzard Entertainment has not announced any details about the next BlizzCon. We recommend that players refrain from making any BlizzCon-related travel plans at this time.Although no dates have been confirmed, this latest update seems plausible, the Anaheim Convention Center is the usual location and Blizzard usually book the venue between August and October. Don’t book those plane tickets just yet until we get something concrete from the powers that be at Blizzard.
