A few more details about Microsoft's upcoming Windows Marketplace for Mobile have been released, just after the Worldwide Partner Conference. As Ars Technica reports, the Marketplace will be open to all Windows Mobile 6.x users by the end of this year, and Channel 9 has stated that it will start taking submissions on the July 27.
The fact that all people running version 6.0 and above of Windows Mobile will be able to access the Marketplace is quite an important one; Microsoft apparently estimates that this will mean 30 million people will have access to it, a comforting thought for developers. If you're interesting in knowing which countries will be able to use the Marketplace at launch, they're here: Australia, Austria, Belgium, Brazil, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong SAR, India, Ireland, Italy, Japan, Luxembourg, Mexico, New Zealand, Netherlands, Norway, Poland, Portugal, Singapore, Spain, Sweden, Switzerland, Taiwan, the UK, and the US.
The Marketplace will open this fall, and at the same time Microsoft will be launching a new advertising campaign that'll show off the new Windows phones to consumers. We've included a video (in Silverlight) of Channel 9's walkthrough of the Marketplace:
