Do we really need that many controls in Silverlight?

I was digesting Scott Gutherie's blog on Silverlight 2 Beta 2

We ultimately expect to ship over a 100 controls for Silverlight.

It really made me wonder, do we really need that many different types of controls built-in with the default Silverlight installation?

Beta 2 now has around about 30+ controls, and the only one that I've noticed is missing, is the combo-drop down list control.

I'm guessing if they really plan to end up with so many controls, then perhaps they'll start by porting across all the various controls that currently WPF have and Silverlight doesn't.

Edit:

Oh and some sort of Menu control
