It has since been removed and now leaves just an "error" message. Suspicious, VERY suspicious.

Could this mean a debut trailer on 4/28/12?!?!?!?

Analysis:
-Return for Debriefing implies a sequel (Black Ops 2).
-it also implies the CIA wants Alex mason to return after the events of Black Ops.
-More than likely well see a Trailer on May 2nd (Wednesday)

This appears to be a new killstreak featured by FPSRussia:

The url must be whitelisted, but it does for sure show that they have something there. This probably means big releases in the near future, but for right now you have to be whitelisted to be able to view the content.

This looks so real, but most believe it is fake. It navigates like a real menu, but it seems waaaaay too early for something like this to be leaked. What do you think? Raw Zombie Menu Video: [You must be registered and logged in to see this link.]
