Canon's long-expected EOS 50D replacement may finally be close to a launch if a rumor from a historically reliable source is true. The tip said on Wednesday that the camera, informally known as the 60D, would have an 18-megapixel CMOS sensor. It should also have unique feature that doesn't exist on any other Canon DSLR, but whether this would be GPS geotagging or another camera isn't known.
