I get the distinct feeling that as E3 grows bigger, it is increasingly becoming a show aimed at the 'expanded audience'. Predictably, the 'hobbyists' are up in arms declaring e3 overall mediocre. But that is why E3 is full of multimedia capabilities, storybook and Nintendo Land and the likes. This is the chance that these companies have to get their products and ideas showcased outside the industry media.
I think Nintendo wants CNN to report on the tablet controller and Nintendo Land. I am guessing their strategy is that getting news of the next Call of Duty out to the 'hobbyists' doesn't require E3 stage time. Why they can't even be bothered to include the logo in a teaser trailer or even in the launch window title list they provided I can only see two reasons. Either there is so sort of deal struck that Microsoft gets first dibs at announcing the game, or more likely in my mind. A specific strategy to try to generate as much excitement as possible closer to launch.
I am guessing that is why there is no price announced or no hard launch date. Nintendo wants to drop some bombs when they do announce these things. So they can make a big splash before the holidays and destroy all.
