What report? From whom?
"Windows Phones, ARM-based Windows tablets/PCs, phablets, and other kinds of devices"
Of course not, Windows 8 does not have a desktop for these devices either. Only for x86/x64 desktop/laptop machines. A "new Windows 9 sku" simply means another product differentiation in their product line. Each service pack of Windows 6 for example has its own sku. Nothing shocking about it.
And unless you are a corporate customer, why are you still running "legacy Win32 apps"? 64 bit apps run far better.
