With COD4 still so popular, Activision and Treyarch needed to take the series in another direction if they wanted to see another installment sell well this fall. Since the announcement of Call of Duty: World at War there really hasn’t been much seen of the game. Sadly while the teaser trailer does give us a short glimpse of the game, it is only that, a teaser. So for those of you who haven’t gotten the trailer from the Marketplace, GameTrailers Television has a teaser trailer up too (which is embedded after the break due to GTTV’s flash player being a bit finicky these days.)
