A teaser on the series official page has officially announced that a worldwide Call of Duty reveal will be happening on May 1st.
Activision had previously confirmed that a Call of Duty title would be released in 2012. A leaked listing by Amazon.com about a month ago suggested that the new title could be Black Ops 2.
If there was any doubt about the announcement being Black Ops 2, some sleuths over on the NeoGAF forums should take those away. According to them the source code for the teaser contains the following text.
“2012 Activision Publishing, Inc. Activision and Call of Duty are registered trademarks and Black Ops is a trademark of Activision Publishing, Inc. All other trademarks and trade names are the properties of their respective owners.”
Keep in mind that it isn’t confirmed that the announcement really is Black Ops 2, but all signs seem to point towards that. Tune in May 1st for the official announcement.
