The latest noise reduction advances seem to be sparking another round in the megapixel wars. Sony and Samsung are off the mark with 20+ megapixel interchangeable lens cameras. The Sony has some 24 MP translucent-mirror cameras and a new NEX 7, while Samsung just has their 20 MP mirrorless camera. I am curious to see if Canon retaliates with a high-megapixel rebel in the near future. I honestly don't care much about more megapixels, but marketing people probably do care. I am waiting on a rebel-sized camera with better controls or a 7D style camera with a swivel screen and fast AF in live view.
