A GameStop employee has leaked a marketing stand promoting the next Call of Duty. The image is very similar to a poster that was leaked a couple of days ago which urges the reader to "RETURN TO DEBRIEFING" on May 2nd. The new game is also referred to as Call of Duty: Eclipse and not Black Ops 2, suggesting that Treyarch may be listening to fan feedback from the Call of Duty: Iron Wolf feedback earlier this year.
A Norwegian Game Store has posted a link to "Call of Duty: Eclipse" back in March, however it has since been changed to Black Ops 2.(Source)
