Megapixels stopped getting much mention a few years ago
But in the last year or so the megapixel wars seemed to have returned with a vengeance. Maybe that's because people realized that more pixels meant they were smaller and collected less light / more noise, or maybe because they started competing on the number of cameras.
Either way we're already reaching diminishing returns in number of cameras so I guess it is back to the megapixel wars and I guess they hope people have forgot about the reduced dynamic range smaller pixels guarantee.
