Future of Digital Cameras

Where does the digital camera technology heading to?

From the article:
There's the end of the megapixel race. "In compact cameras, I think that the megapixel race is pretty much over," says Chuck Westfall, director of media for Canon's camera marketing group. "Seven- and eight-megapixel cameras seem to be more than adequate. We can easily go up to a 13-by-19 print and see very, very clear detail."

If not pixels, what will motivate us buy new camera every couple of years?
