The Sony Alpha A900 is out, with a full-frame 24.6 megapixel sensor with built in IS. I'm the sort of person who thinks that this, paired with a 50mm 1.8 lens, would be fairly neat. You can bet that Canon was probably waiting for this to occur before they announced their 5D replacement, tho.
There's been some hope that we're going to stop seeing the fairly stupid megapixel race progress and might actually see some new features in cameras. As usual, it didn't happen this PMA.
