Canon's 120MP Camera Sensor
A lot of cameras are sticking at 24MP because that's where a lot of lenses start to reach a weak point. Also, file size to utility becomes a consideration because most people expect cloud/sharing. I feel like 100+MP is going to be an enthusiast thing for a long time. It seems a lot like car speeds. Every car sold today can go over 100 miles per hour. Some people still care about how fast their car can go, but most don't really think about it or even know their car's top speed.
