Windows Phone 7: Hands on Demo.

Interesting video (from Channel 9) showing a preview of the winPhone 7 OS.

Get Microsoft Silverlight

I am just a bit worried about the localized version of Bing. So far I have seen it working in the US. Does that mean that Bing will be updated for a worldwide support or that the winPhone7 will be available only in the US until it is done?

Thoughts?
