Having been active on the Internet before it was the Internet (e.g. ARPANet, and a few other early iterations), I've watched the crowd mentality do its reality distortion thing every now and again. Once in awhile the silliness hits the Nikon world. Case in point: the so-called "Nikon Road Map".
A quick read of the specifics of the document should be enough to convince you that it is almost certainly not a Nikon document, let alone accurate. Yet it seems every photo-related site now quotes the document or has a discussion of it (now including this one). You'll note that I've taken to identifying items on my main page to make it clear what type each one is.
My opinion of the Nikon Road Map? Fan fiction. In the details you'll see that many things just don't align with reality very well. For example, a CAM380 AF sensor would indicate a focus sensor with significantly less focus sensing area than even the D40, D40x, and D60, which have three AF sensors. Since the same document says the D3000 is a seven-sensor part, this would mean really, really tiny focus points, smaller than anything Nikon has ever done. Thus, the details are not believable (nor do I believe that the D3000 uses a seven-sensor AF part).
