It looks like Microsoft may announce plans to introduce Silverlight for the Xbox 360. The company will apparently detail its plans at the MIX11 conference next week in Las Vegas. This has been planned for months and Microsoft had already revealed that it was planning to bring Silverlight to the Xbox.
This seems like a good plan for Microsoft, to bridge the gap between it’s mobile, PC and Xbox platforms. It ties in with their plans for Windows 8 as well.
