Blizzard Entertainment have announced Foo Fighters as the musical guests at BlizzCon 2011.

The press release was released yesterday, announcing the headliners for the closing concert of this year’s BlizzCon on the 21-22 Oct.

Foo Fighters frontman Dave Grohl said: “We’re pretty sure that in the future, music historians will look back at BlizzCon 2011 as the unquestionable pinnacle of Foo Fighters’ long and illustrious career,” which you can’t argue with, they had Ozzy himself only two years ago.

BlizzCon first started in 2005 with only about 8000 people attending, this year’s Con is looking more like 30,000+ people, and the guests for the closing concert included Level 60 Elite Tauren Chieftain, a comedian, and The Offspring. Since then, it has just got bigger and bigger, with Ozzy Osbourne, and the D (Tenacious D) rocking the halls of Anaheim – just as Foo Fighters will do next month.

As of BlizzCon 2009, it was available live via internet stream and covered both days as well as exclusive interviews and discussion, this was available for a much more reasonable price of around £25, and the system is much improved as you now have choice over four halls on what to watch and when, plus it counts as a front row seat to see the closing ceremony.

This year, expect to see some Starcraft 2 updates tournaments from literally the best players around, plenty of World of Warcraft coverage, and probably most significant this year, Blizzard’s third franchise which has just gone into closed beta, the much anticipated: Diablo 3.

BlizzCon will run over two days on the 21 and 22 of October, and there are still an unallocated number of virtual tickets available from the website, which will give you great views for developer panels, competitions, tournaments, and the closing ceremony, not to mention the World of Warcraft in-game pet, Murkablo!
