You aren't missing much on this one. They seem to be only showing off their upgrade installer. They may have just added screens to the existing one, but it has a progress indicator now.
The new Recycle Bin icon looks like something my 5-year-old would have drawn when she was 3. The start menu and taskbar seem, to me, to have a bit more translucency.
Icons and installed programs carried over well, except for the task bar, which Windows put back to what they wanted it to be. I guess they think people really should want that stupid search bar hogging space at all times.
