Last time I looked the vast majority of Windows users don't need the console (or even a terminal emulator) and don't tend to compile software themselves or use large parts of the usual UNIX tools. So there are very few users who migrate away from Windows due to that and thus very little incentive to invest a significant amount of effort and money in that.
Then there is the point that Windows is very different from UNIX (even though you can support POSIX as an API layer alongside Win32). As Jeffrey Snover (one of the architects of PowerShell) once put it: They thought about that but noticed that UNIX tools won't help any Windows sysadmin as they are good tools to work with a UNIX system that's mostly based around text files scattered throughout the file system. But they don't work so well in managing Windows which is more centered around the registry and other mechanisms.
