Sad_Dave: see? there are important reasons behind the comments and speculations here. Generally, the ones who expect all features on one camera are without a firm grasp of tradeoffs, target markets and cost consequences.
as far as the discussion itself goes, - A wildlife camera should be optimized for the environments it is expected to be used-- outdoors in less than ideal conditions. It should not be have the ability to place a portion of its hardware in a mechanically vulnerable position, increasing chance of equipment failure in enviroments more hostile, for example, than an indoor birthday party. Moreover, a wildlife/action 'tog is not likely to appreciate the cost, durability, weather sealing, and ergonomic consequences of having such a screen but simply avoiding its use.
That said, the general purpose consumer who wants to chronicle family events, adding a few cool portaits, landscapes, and macros along the way, would likely be happy with a general purpose camera with an articulating screen, especially if there is no desire to chase moose in the snow.
I do acknowledge (and even suspect) that if Canon strengthens the wildlife/sports orientation of the 7D even further in the 7D2, and perhaps even produces a worthy successor to the 1D4, that there will be some disspointed consumers who want the status of a single digit camera with the consumer features of the xxD
