Bing announced they have greatly expanded their autosuggest engine to include a lot more types of queries, such as brands, movies, albums, places, software, sport teams, animal species and more.

Bing also explains how it works:
Bing utilizes an underlying technology we call Satori that understands the relationships between millions of people, places and things providing you with a more useful model of the digital and physical world. All of this computational power allows you to select the most appropriate choice in a matter of milliseconds.
Of course, for search marketers, keyword autosuggestions are a great keyword research tool.
