Activision believes Call of Duty: Black Ops 2 has the potential to become the best-selling game of all time.Speaking to analysts and investors last night following the publication of the company's third quarter financial results, Activision Publishing CEO Eric Hirshberg said (via Seeking Alpha): "Developed by our team at Treyarch, the game has the potential to be [the] biggest selling game of all time, to passing Call of Duty: Black Ops."And the buzz to date has been tremendous. YouTube views are nearly double those for Modern Warfare 3, Facebook engagement is up more than 150 per cent and the Black Ops 2 multiplayer reveal from GamesCom became the largest live stream event in Xbox Live's history."And the Nielsen's first choice survey, which measures both unaided awareness and purchase intent, Call of Duty: Black Ops 2 tops the list and is at an all-time high for the franchise."Hirshberg continued: "Looking to the launch, we're working incredibly hard with all of our partners around the world to make Call of Duty the biggest entertainment launch of all time for the fourth consecutive year."Pre-orders for Black Ops 2 continued to track ahead of Modern Warfare 3, which is no small feat given that MW3's was the most successful pre-order program of all time."However, Hirshberg went on to acknowledge: "There are always risks when trying to grow a brand that is already performing at record-setting levels. So while we're optimistic, we're still planning prudently. We look forward to sharing details about our successes with you over the weeks ahead."Activision has confirmed a Black Ops 2 release date of November 13.
