Well the last few days have already seen some big announcements related to maps, with Google showing off their improved version of maps with offline support and Apple going a step further and displacing Google maps with their own Maps applications with 3D navigation support.

With the top two mobile platform making their moves, it was time for Microsoft to respond and they did by replacing their default Bing maps application with Nokia’s awesome maps application for all phones with Windows 8 and hence making this a three pronged mobile navigation war.

Though, there is not yet any clarification on what would that app be called and whether it would retain the Nokia tag in its same. Retaining the Nokia tag on a default Windows Phone app might not be a great idea, but you never know until there is an official announcement regarding the same.

The app would also bring Nokia’s 3D navigation and transit directions for all the Windows 8 devices. The transit info will make the Windows Phone maps application more alluring than Google’s solution considering that they do not have that detailed transit info yet and Apple is relying on Tom Tom to provide the transit information.

It is an interesting decision, considering the fact that Nokia maps is one of the important apps that differentiates it from the rest for the manufacturers in the Windows Phone platform. Though if the move is executed, it would further underline the deep partnership that Nokia and Microsoft share with each other.
