Rumor: Nintendo Prepping More Non-Games For DSiWare
Posted by Jon Wahlgren
Maps and dictionary wares may be in the works.
Without a built-in GPS or non-WiFi Internet connection, the Maps program could face some issues as to how useful it would actually be (unless the maps are of the Mushroom Kingdom, which would be super useful). A dictionary probably wouldn't face any hardware restrictions and could actually be pretty useful if you don't have a paper version around and need to look up the definition of decalcomania.
Maybe they should just release that Mushroom Kingdom map. Or a Pokedex!
