The official website also confirmed that the game is set to be released on November 13, 2012, and links to a (currently unplayable) Worldwide Reveal trailer - that's expected to change once the trailer airs in the US later today.
It's fair to say that so far the existence of Black Ops 2 has not been the best kept secret, but this confirmation means Call of Duty fans can now rest assured that another chapter in the record-breaking series is on its way.
Rumours started after Activision acquired the rights to the domain name for Black Ops 2 back in January. This was then followed up by a controversial incident involving French website Gameblog.fr. The site stumbled upon a listing for the game on Amazon, and had a public argument with Activision following their refusal to withdraw their coverage.
A leaked poster told us the date of the announcement, and the website has now also preceded the big reveal.
Last week a trailer hinted at a futuristic setting. The trailer included a technologically advance Quadrotor, images of which can be found on the official site. It would appear that Treyarch did indeed opt for a near-future setting for Black Ops 2.
