The next Call of Duty game about to blow the doors off

Here's a chance for Activision to redeem itself after the Black Ops Vita disaster. A new teaser site, UnexpectedReveal, is up counting down to a reveal next week. After the initial flash of a screenshot, and the whine of a night vision display (I think), among the site code are the tags, "Call of Duty, Activision, Modern Warfare, Teaser Trailer, Infinity Ward, Sledgehammer Games, Neversoft, 2013 March 21, Countdown, MW4"

That's pretty conclusive, perhaps for a major new update, or the next game in the series. But there's not format information, but the game is most likely to cover PS3, PS4, X360 and XNext. While I'd put the odds of a Vita version as pretty slim, given the farcical Black Ops Declassified game has reclaimed the No. 1 spot in the Vita retail and PSN charts, if it is earning enough for Activision, to justify some investment, then there's a little hope.
