It looks like the days of the Windows Phone Marketplace are over, because Microsoft has decided to rebrand it the Windows Store. The move is just another piece of the puzzle that brings together Windows 8 and Windows Phone. With the introduction of Windows 8, Windows is moving into the tablet space, and Microsoft wants to bring together that space with the Windows Phone space it has been building.
Along with the rebranding to the Windows Store, the website will be getting an upgrade to bring it more on par with offerings like the Google Play Store. There will be a redesigned Spotlight section, as you can see on the right. Search will be getting a boost to be smarter about finding what you want if you've made a typo, as well as finding related apps even if your search term isn't in the title of the app.
The Top Free and Top Paid sections will be renamed "New+Rising" in an effort to differentiate wording from competitor offerings, and there will be a new "Best Rated" section to promote quality apps. Additionally, "racy" apps are becoming less visible in order to make a "friendlier store", so you may have to dig more if you want the "sexy" apps.
The blog post doesn't say when the changes will roll out, but it seems reasonable to expect it in time for the Windows 8 launch
