There's usually as much fun to be had before an Apple product launch as there is after, and this upcoming iPad 2 device is no exception. The latest scuttlebutt it has succumbed to comes courtesy of some cases that have cropped up in China -- AppleInsider and MIC Gadget have independently found iPad 2 shells that feature nearly identical cutouts -- with the resulting allegations pointing toward a rear-facing camera, an SD card slot, and perhaps even a Mini DisplayPort receptacle. Our own sources have confirmed the former two, but the latter, a miniaturized video output already featured in MacBooks, is a new development and less of a certainty. Then again, looking at the size of the hole leaves few alternative options (and a USB slot is extremely unlikely), so we're willing to believe that a Mini DisplayPort will be an inclusion Apple makes for the sake of offering choice -- even if it prefers you to send your video streams over an untethered AirPlay connection.
