Activision Blizzard today confirmed that StarCraft II will not be released in 2009.

As part of its April-June earnings report, the publisher has indicated that the release will now most likely take place in the first half of 2010.

The delay in the release of StarCraft II has been attributed to the requirement to relaunch the upgraded Battle.net online-gaming service at the same time, although it seems likely that the extended release window will be used to further improve the game, and allow a comprehensive beta testing period.

Despite the delay, the financial future looks bright for Activision Blizzard - they've reported US$1bn revenue for the quarter ended June 30, 2009, with two of the top-five best-selling titles in North America and Europe - Guitar Hero World Tour and Call of Duty: World at War. With Call of Duty: Modern Warfare 2, Guitar Hero 5, DJ Hero, Band Hero, Tony Hawk: RIDE and Bakugan Battle Brawlers due before the end of the year, they still seem to be in a good position to capture a large percentage of holiday sales.
