Fuji recently unveiled a prototype of a digital camera with Wi-Fi capability built in. The interesting part of this story is that the camera they displayed is the exact style of the one I own. It features a compact flash and a smart media slot. If Wi-Fi is not actuaully built into the camera it could use the compact flash slot for that and the smart media slot for storage.
Other possibilities include connecting to you laptop and saving files directly to your harddrive or working as a team where one person takes the photos and the other sits nearby with a laptop and pulls the pictures off the camera and edits them on the spot. While not terribly practical for the average user, I think this could work well for professionals.
