As presumably the successor to the aged 5D, the 50D has a lot to live up to with new competition from the Nikon D700. Unfortunately for Canon, it looks like Nikon's got them beat in everything buy megapixels (Canon: 15mp, Nikon: 12mp), fps (Canon: 6.3 fps, Nikon 5-8 fps), and body material (Canon: metal alloy, Nikon: polycarbonate). Nikon's still going to run the table with their higher ISO, faster auto-focus, and more fps (with vertical grip).
