New Call of Duty reveal coming May 1

Activision is gearing up for a new Call of Duty game announcement. The publisher's official Call of Duty site has changed overnight to reveal a new splash page detailing a forthcoming announcement on May 1.

New Call of Duty announcement coming May 1.

On the page, the headline "World Reveal" is displayed beneath the Call of Duty logo and is accompanied by a countdown timer. The tagline reveals the announcement will be made on May 1 during the NBA playoffs on TNT.

Zooming out of the splash page, the site reveals 14 smaller windows, currently all blacked out with the word "Classified" over the top. However, clicking on each window reveals that different windows will be "unlocked" at different times over the coming week leading up to the May 1 announcement.

Last week, a marketing poster from a retail source surfaced, hinting at an upcoming Call of Duty: Black Ops 2 reveal. The game has already been spotted on French and Spanish retailer websites, and an employee at a contract art studio listed work for Black Ops 2 on his resume.

Call of Duty: Black Ops remains the most successful Call of Duty game to date. It has sold more than 25 million copies through August 2011 and became the best-selling game of all time in the US by the March following its debut.

Last year's Call of Duty: Modern Warfare 3 initially sold at a faster pace than its predecessor but failed to make the NPD Group's Top 10 list in March, its fifth month of release.
