Microsoft teases May 4 reveal, possibly Call of Duty related (update)

Today, Microsoft teased a forthcoming Xbox reveal, scheduled for May, that might hint at the next entry in the Call of Duty series.

Xbox community manager Raj Patel tweeted the above image today alongside a cryptic "Hmm..." Morse code from the image translates to "Presented by Xbox, 10 am PDT/1 pm EST May 4th 2015." The first week of May is when Activision typically announces its Call of Duty plans for the year, usually with the assistance of Microsoft. Last year's Advanced Warfare reveal happened on May 2, with Call of Duty: Ghosts announced on May 1 the year prior.

Call of Duty announcements also often coincide with the NBA playoffs. This year's NBA Conference Semifinals are slated to kick off May 4.

We've reached out to Activision for confirmation of its Call of Duty plans.

Now that the Call of Duty franchise is being developed on a three-year cycle by three core studios, this year's entry is likely being developed by Treyarch. The studio's last game was 2012's Call of Duty: Black Ops 2.

Update: Hours after posting the image to Twitter, Patel said the image was "unofficial."

"Earlier I posted an unofficial (not from Xbox) image to see what others think of it, not as an endorsement or tease. Sorry for any confusion," Patel tweeted.
