Next Halo Hits March 2007
Microsoft plans for wide-open spring 2007 launch.
by Douglass C. Perry
March 30, 2006 - The next Halo is coming in March 2007. According to a Microsoft source who asked to remain anonymous and a second source close to the company, IGN today learned that Microsoft will publish the next Halo game (as predicted in January) in March 2007.
When phoned, Microsoft declined to comment. While the holiday season remains the most important set of months to publish a game, the first calendar quarter of the year is proving to be bigger and more prominent in sales. Microsoft intends to innovate, challenge traditions, and to use its own "playbook" (as Microsoft's J Allard has said time and again), and slotting Halo 3 (or Halo Forerunners, or whatever April Fool's gag you choose) in March 2007 is likely to shift consumers' priorities. That anticipation will overlap with the first few months of Sony's and Nintendo's launches, cutting into their building stages, and shifting eyes toward and opening wallets for Xbox 360.
By theoretically shifting Halo to next spring, Microsoft thus allows third-party companies a better chance to shine independently of Bungie's uber shooter during the fall 2006 season. One must wonder, however, why the game wouldn't come out simultaneously with the movie, due in summer 2007. But if Halo 3's alleged March release date is officially confirmed, perhaps the game will leave questions for the movie to answer.
so fuck your rumors about it not coming.
