Yes, it's still there, in the same way that MS-DOS was still there in your shiny new copy of Windows 95. And as with DOS in Win95, the primacy of the new environment lays down a clear marker that Microsoft is going in a different direction from now on, so if the "legacy" environment is the one you prefer you should start planning to either live without it or move to a different OS.

You don't need a weatherman to know which way the wind blows, etc.
