Windows Phone 7, which hasnt even launched in all parts of the world, is off to a quick start. The WP7 marketplace now has over 12,000 developers, a positive sign for Microsoft that their new mobile OS is starting to take hold in the developer community.

WP7's future depends on the ability for third party developers to offer all applications that a user not only depends on, but expects in this era of mobile operating systems. However, this type of success shouldn't come unexpected considering that Microsoft is throwing hundreds of millions of dollars behind the marketing campaign for WP7.

According to fiercedeveloper.com, "More than 12,000 Windows Phone 7 developers have now registered to market their applications via Microsoft's Windows Phone Marketplace storefront, slated to go live later this month. According to Microsoft, WP7 developer registration increased close to 40 percent over the last month alone."

As Windows Phone 7 continues its launch across the world that started in New Zealand with the first phone sold in the world , followed by the Australia and Europe, Microsoft is going head on into an intense phone platform battle, where the company has been lagging behind for many years.
