This isn't really a ground breaking revelation but something that MS has been hinting at for months if not years. Win32 was never suppose to be so tightly integrated in the Kernel, it was suppose to be a user mode subsystem just POSIX.
MinWin was a kernel cleanup effort that was suppose to be part of Longhorn and then Win7. If MinWin is finished in Win8 then Win32 would just be a subsystem along side Metro and neither would be dependent on the other or necessary for the other to operate.
I can't find the reference but I remember reading somewhere a few months back that Win32 may not even be installed by default in Win8 and that it would only be installed when you attempted to load an application that needed Win32.
