Pre-PMA 2007: Nikon has chosen today to announce its new Coolpix lineup, debuting at PMA in a couple of weeks. By far the most interesting new model is the P5000, a fully-featured 10 megapixel camera with stablized 3.5x zoom, 2.5-inch screen and very compact design. Could this be the camera to put Nikon back on the high-end compact map?
