I think pixels are being added simply because consumers think
megapixel counts are all you need to know.
Given that current image sensors are not up against a basic limit,
Moore's Law will apply, and we can expect performance to double every
18 months or so. So, you will be wrong. The only question is how
long it will take to achieve this.
