As we all know Zune Marketplace is coming to the Xbox 360. Through the magic of Microsoft Silverlight, instant-on 1080p content will be available when the Marketplace comes to the Xbox 360; but did you know that you could check out the 1080p streaming now? All that you need are a compatible web browser with Microsoft Silverlight installed. As you’ll see in the demo, you can play around with the bit-rate to see exactly how the technology will work, and compensate for changes in your Internet speed. Check it out and let us know what you think, is this enough to replace Blu-Ray in your life?
