Developer interest in Windows 8 is stagnant, new line of worry for Microsoft 14 years ago
It's very expected situation. Developers don't like WinRT and will stick to Win32 forever because Win32 is open platform (anyone can develop for it without paying Microsoft) and WinRT is closed platform where Microsoft can apply censorship in their "app shop". No developer in the whole world wants to be thrown out of that "shop" and supply ideas for next version of Windows for free.
