Though not very exciting for most of us, Canon have a announced a studio version of the EOS 7D, called the EOS 7DSV. It's basically a regular EOS 7D, but with the ability to lock in (or out) certain camera features. When shooting in a studio or with multiple photographers, this can ensure consistent results.
The EOS 7DSV can also utilize a barcode reader to read barcode data and write it directly into the image's EXIF data for better tracking of multiple images shot at large events.
The EOS 7DSV is really intended to ease the workflow of commercial photographers shooting things like senior portraits, where a lot of images are shot and it's important that the images are easy to track, identify and organize.
