Now this is Big! We could experience location based games in WP7! XBox Live in WP7 (Windows Phone 7) will come alongside Bing Maps. This opens the doors of location based gaming in WP7. It will be the Xbox gaming experience powered by Bing Maps right on your WP7 device. Considering the success that Xbox Live and Bing Maps are already, this could be yet another killer feature for Windows Phone 7 and could possibly be the next generation of location based games on mobile devices.

As an example, Microsoft have released a screenshot of Crackdown 2: Project Sunburst for WP7 game that highlights the potential of Bing Maps:

Xbox Live on WP7 with Bing Maps

Crackdown 2: Project Sunburst is a tank-like game that uses Bing Maps as backdrop.

Microsoft plans to associate location to your online profile using your device, that will then be used in location based games. To achieve this, Xbox Live, WP7 and Bing Maps teams are working closely. So we can expect something really good.
