Grace, The Chinese and other Asians will use lower cost lower resolution CMOS image chips. they are under $5 each, how much can the rest cost.
The only limit they are approaching is the pixels need to be a certain size so they need to make larger diameter CCDs to get more pixels once they reach the optical limit for CCD pixels. The same limit that stops light microscopes from imaging smaller and smaller without limits, the wavelength of light.
This will cause the cost of larger pixel cameras to plateau and even grow unless the improvements of % yield offset this. Yield is also important as perhaps 75% of CCDs are rejected for critical uses and sen to cheaper markets where the bad pixels are mapped out with a mapping rom. Sure this makes a permanent flaw, but as long as it is a few isolated pixels they find that lower end markets will tolerate it.
Even the Video block on Sony Betacams has a few mapped out bad pixels in the outer areas.
As you say, it is a fast freight and it is not stopping.
