Looks like the msn.com/preview has been updated, or at least the “my apps” portion of the home page.  Before, there were three tabs, for Facebook, Twitter, and Windows Live, and a separate Hotmail section, but now two new apps have been added: Weather and Bing Maps:

Clicking on each of the apps opens a live fly-out window, in this case showing a live Bing Maps that you can interact with, including traffic information, but My Apps shows updated information for each of the apps even before opening them up.

This is a nice improvement over the first attempt at My Apps, although interestingly the Windows Live section has apparently been dropped.  Here’s a screenshot from our original post on the new (US version) MSN.com preview:

The new page already has a Bing Maps tab (although without the nice live map in the flyout) and a Weather tab, so we’re not sure why they need to be on the home page twice, but this preview is obviously still a work in progress.  Notice anything else new? Leave a comment!

(thanks for the tip, Dirk!)
