I know nikon has made one with a camo cover in the past, but I wouldn't base the selection to highly on that priority. There are a number of things available to either cover a camera or hide it away.
If you wanted, you could even paint it carefully with hobby paint, considering that may void warranties.
I carry an olympus point and shoot most of the time, and my SLR when space allows or image quality is key. For snapshots though, many digital point and shoots will do you well. Just keep it in the pocket, and you'll be glad you didn't have camo when you drop it in the thick stuff!
