No. Despite the Washington Post's provocative headline, Apple's no more "secretly working on an iPhone camcorder" now than they were "secretly working on an iPhone camera" in 2006.
Technology advances. Early digital cameras had very low resolution, now they're in the double-digits for megapixels. When VGA cameras were no longer of any value as stand-alone products, they were integrated into cellphones. Now 2, 3.5, 5 megapixel, and even higher resolution optics are becoming likewise obsolete as anything but integrated options, and so are finding their way into the iPhone, Nokia, or SonyEricsson devices.
