Bing has been testing new home page design tweaks, a new user interface for the vertical search engine links this week. Instead of having the links to the vertical search properties on the middle section left hand side of the page, the links are at the top.
The first screen shot below is of the new home page with the search verticals displayed on the top instead of the list displayed over home page image:

Microsoft is also testing a new header for search results -- screenshot is below:
A Microsoft spokesperson said, "We're constantly updating and refining the Bing search experience, and before any changes are implemented they undergo intensive testing and experimentation to ensure the best possible user experience. However, we have no news to share at this time."
