"Remember when a 6-megapixel digital camera was a professional tool? No longer. Olympus and Konica Minolta are both announcing consumer-friendly 6-megapixel cameras priced under $500. Olympus's C-60 Zoom will ship in April, with a $450 estimated street price. Konica Minolta's DiMage G600 won't be out until May, with pricing expected to be "under $500," the company says. Olympus also is announcing a low-end, 3.2-megapixel camera. The D-395 will also be available in April, with an estimated street price of $150."
It appears that these 6MP cameras are aimed at that advanced amateurs, though they do support automated point-and-shoot as well. I think we can safely say now that 6MP is going to be commonplace.
