All of Metro's XAML based witchcraft evolved out of Silverlight, although it's not branded as Silverlight to avoid confusing stuff.

The branding is WinRT .NET+XAML.

WinRT is a COM based runtime. It may be very source compatible with Silverlight, but it is by no means just a "rebranding" of Silverlight.
