First, congratulations to Nokia and Microsoft for the feat, really. I take back some of the things I said about Elop. But I still think he looks like a complete &^%$#.
Second, This isn't that surprising, I've seen it happen before. AMD and Intel about a few years ago. All Intel had was Prescott, a overheating Pentium 32 bit single core processor while AMD had a dual core 64 bit marvel. But then Intel pressed on the gas paddle, and we all know how that turned out. [Even though AMD broke my heart multiple times, still most of my rigs are AMD]
Anyway best luck for Microsoft, I've nothing against XAML (I still think you're a fool to use it), now if you can stop suing everyone who makes cell-phone that aren't WP.
