Windows Phone 7 will support 5 languages initially
Windows Phone 7 will be available regionally this holiday season and beyond. I’m happy to say that Windows Phone 7 will be well represented in countries around the world this holiday. During initial availability, Windows Phone 7 will support 5 languages; English, French, Italian, German and Spanish.
The Windows Phone Marketplace will support the buying and selling of applications in 17 countries; Australia, Austria, Belgium, Canada, France, Germany, Hong Kong, India, Ireland, Italy, Mexico, New Zealand, Singapore, Spain, Switzerland, UK and United States.
Now we need partners that will actually carry WP7 to those countries. I think it will happen, but it might be a while before it becomes broadly distributed internationally.
i don't think that the language support is much of a concern,
what i really looking forward to see is the paypal support coming onto the windows marketplace, that would attract many customers for sure.
