<p>Today I was listening to the <a href="http://www.hanselminutes.com/default.aspx?showID=145" rel="nofollow noreferrer">Hanselminutes show about .NET 3.5 SP1...What's inside</a>, and they twice mentioned the Office 2007-like Ribbon control that is included in Visual Studio 2008 Service Pack 1.  </p>

<p>I am very interested about this, as I was previously looking at purchasing this from a 3rd party vendor (likely <a href="http://www.devcomponents.com/dotnetbar/ribbon-control.aspx" rel="nofollow noreferrer">DevComponent's DotNetBar</a>).  However, I did some research this morning and have found nothing about this control being included for use with C# and WPF.  Does anyone know more about the included Ribbon control and whether or not it is available for C# or WPF?</p>

Yeah I did a double-take when I heard them say that too.
The ribbon control, along with a DatePicker and DataGrid, are being developed out of band
over here
on CodePlex. I'm not sure why Carl and Scott were suggesting that it was part of the SP1 release.
