I spent a bit of time in the session on the new C++ language syntax, and I saw a similar presentation a few weeks ago back in Redmond. The current release of VC++ uses an extension syntax to "add on" the managed (ie clr) concepts onto the existing C++ syntax.

For Whidbey, the C++ team has ingrained the managed concepts deeply into the language syntax, which should make it easier to write managed code using C++.
