off roading with apple maps?

do you think apple maps will become downloadable to the iPhone? if they added waypoints and the ability to download the hybrid version of their maps i don't think id use any other maps. love to off road and hike but using the phone for navigation requires another map program. if apple allowed downloadable maps wouldn't that make them more useful to customers and more valuable to apple? what would all you on the verge use offline maps for??
