Nokia Maps 3.06 - Why is the new map design not available for Nokia Drive on Windows Phone, or for Nokia Maps on Symbian and MeeGo?

At first, the new design will be available at maps.nokia.com, m.maps.nokia.com and on Nokia Maps for Nokia Lumia (using tile maps). Eventually the new design will be also included in an update for Nokia Drive on Windows Phone (using vector maps), for which consumers can download maps for offline use.
