Given what MS did to powershell to make *nix commands like ls work (i.e. make them plain aliases to the equivalent powershell commands without any attempt to convert flags) I wouldn't get my hopes up. (Nothing could have prepared me for the disappointment of typing ls -l and getting an error.)

I hate to be a pessimist but $20 says they're just making it so they can technically claim that Windows supports commands Linux users are used to and therefore that Linux users should have no trouble in a Windows environment.
