We know how patiently you’ve been waiting for this day, but it’s here. It’s really here. Microsoft Windows Embedded Automotive 7 is out, appearing in the download queues of “select car makers and suppliers in the automotive industry.” What does it offer? Why, Silverlight support for fancier UIs, real-time text-to-speech technology, and better expandability for third-party plugins. In bigger news, Microsoft is confirming that it is the brains behind the Nissan Leaf‘s Information Hub, which not only handles infotainment duties but also gives charging status and power consumption figures. Finally, the MyFord system is going global, shipping to Blue Oval vehicles in Europe and Asia in 2011. That’s after 2.5 million Sync-equipped cars have hit the road. Highway domination? Nearly complete.
