Blizzard Entertainment's BlizzCon event is actually starting to turn into an annual affair. Today the developer announced that the 2010 edition of their fan event will be held on October 22-23 at their long time location at the Anaheim Convention Center in Anaheim, California.

There are not a lot of details at this point about the show and that includes when tickets will go on sale and how much they will cost. Last year tickets sold out in a manner of minutes at $125 a pop. Blizzard's fans can expect to have a ton of activities to attend as well as exclusive items on sale. Will we learn more about the future of World of Warcraft? Will we get more details on the next game in the StarCraft II trilogy (the first should be released well before BlizzCon)? Will we get more info on Diablo III? And most importantly will Blizzard finally reveal the first details on their next generation MMO game. Stay tuned.
