New Call of Duty reveal coming in May?

Xbox community manager Raj Patel may have teased an upcoming Xbox reveal that will take place in May. 

Patel tweeted the below image followed by the words, "Hmm...". The morse code in the picture translates to "Presented by Xbox, 10am PDT, 1pm EST, May 4th 2015."

So what could this mean? Well, Call of Duty games are historically revealed in May. And if the three developer cycle is followed, it's Treyarch's turn to take the wheel. The two in the image could mean we're getting a sequel to World at War, but that's pure speculation. 

Hours after posting the image, Patel tweeted again, "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." 

Could Patel have tweeted something without permission or perhaps tweeted it too early? I guess we'll have to wait until May to find out.
