The marketing idea that consumers could judge a camera based on 'how many megas it has' died a while back. It was definitely dead in 2009 when Sony released cameras with Exmor backlit sensors and competed with a similar Fuji offering. In the professional market, however, it's possible to get an 80 megapixel medium format sensor and there are post-production advantages that make this worthwhile for professional use. I wouldn't be surprised if sensor resolution continued to creep up in prosumer cameras as well. There are still benefits for consumers from higher sensor density and resolution, as long as it can be done without introducing noise. For example, slightly less awful digital zoom and the ability to liberally crop.
